Im looking a bit forward in time here . As one can assume building a track only car reqiures the car also to be lightened and therefore on some occasions the interior upholstery is removed (seats, carpets, side panels etc. )

Some items like the seat are replaced with lightweight racing seats, yet when one removes the carpeting and side panels the interior looks very bare and very unattractive.

Im doing up a list for this writing down some ideas iv seen and thought of myself. But my main concern is, would light weight carpeting go into a track only car, since the ones iv seen are mostly bare, except a GTR iv seen on youtube (red one) which seems to still have its carpeting.

I was intending of using some fire resisitant material (silver) at the rear and light weight carpeting and aluminium panels to cover the 'holes' found on the inner body side. I was also thinking of using light weight carpeting on the floors. I am concerned a bit about the reflection the silver fire resistant meterial might give out but this could be eliminated by fixing/fitting a light weight particion between the drivers compartment and the rear while also placing a dark shade of window screen to the rear hatch window and side windows to keep the reflection to a minimum.

I hav aquired a sample of this light weight carpet which seems to be very flexiable and an be turned to any shape, so eact fitting here isnt a problem.

I know I might be adding a few pounds here and there, but this isnt troubling me due to the amount of stuff removed from the car already.

All depends on the racing series you intend to do. Picking the series and studying the regs will direct you to no trim, minimal trim or full trim. Some 'classic' events allow the interior to remain except for a safety cage, race seats and harnesses.

The stock carpet and trim is light enough. 'Lightweight' carpet is not much lighter.

I removed all under carpet insulation and most of the tar which alone is circa 20kgs+.

Ok 1 series called the VGP which organises a 'once' event called the Valletta grand Prix and a number of speed festivals during the year have a set of rules which you can choose your class from.

This organistation mainly focuses on races for classic cars (pre 1975) for which i also have prepared some cars for, but this is another issue.

In this series any car which has been lightened, modified etc will have to run in what they call the E class which is open to pro and pre 1975 modified classics like the 924.

Funningly enough the rules say that the interior can be removed or altered. I have chosen this class to run Porsche no 2 in . So here I can alter the original interior. Funningly enough though this series does not insist that a roll cage be fitted and while also stating that IMO and many others, the circuit surface is very slippery and dangerous

With the other clucb named ICC who organise pursuits and hill climbs the interior is also free (group 2 class 4) yet a roll cage of some sort has to be fitted.

So in both series the alteration of the interior wont realy effect the class.

I agree that the interior under carpet tar is quite heavy yet disagree that light weight carpeting isnt 'that' light. Well at least the sample I have seems weightless.

Although Im realy not that concerned or interested in redesigning the 924 interior, my main concern is to adapt material which wouldnt look out of place in a full time track car interior.

Im doing up the exterior of the car as best as I can while also considering its a track car since Im a bit fussy yet I wouldnt want to ruin the car with a bad looking interior either.

Bear in mind that I do not want a road worthy looking track car( I have 2 Ford Cortina GTand E 1969 model like that) so modifications on both interior and exterior are quite acceptable.

The 924 will be used not more than 10 to 12 times a year.

If you're going for the club racer look, then yes do the lightweight carpet. If you're going for all-out track car look, then carpet will just look silly.

I think 924RCER has the door cards in because they're required in ITB. Knowing him, if they weren't required, they wouldn't be there...

I also like the home-made door cards that Chrenan made. I'm still contemplating door pulls like this in the Club Sport:

OK, No 1, I think 924RACR has a lot of stuff on his car that he would remove if not required by ITB including the body panels...

ideola, I dont wantt to complicate the interior, yet first I think I will have to establish what would go in the car. It still seems to me that a bare interior would not go down well , so I need to think of something which will give the car a track look anyway without adding too much weight.

Iv seen a picture of a 944 racer which has a particion right behind the drivers seat. This might eliminate carpeting the rear of the car, but im not sure if I should use aluminium or some thin marine plywood for this.

This would leave me with the front part/ footwells etc.After some thoughts I have some ideas. For the door panels I was going to use thin aluminium sheets covered with some sort of rexin and therefore obtain the 'Chrenan' look, Though I would use some sort of rexin/leather straps as door pulls. I would also fasten them with allen key headed self tappers placed and seperated evenly, which would give it a different look.

That would leave me with the left/right foot wells which I was thinking would be covered with partialy carpet, and partially with those aluminium foot rests which are seen in rally cars which look something like these-
http://s1081.photobucket.com/albums/j349/iqssm/?action=view&current=2241662-5.jpg

The pedals would be OMP racing pedals which have been ordered, I still need to think of something for the dashboard since it needs some repairs, and I also need to design or think about a centre console which will hold the gauges, on/off swicth, ignition switch battery main switch, since the original was badly battered up. I was also thinking of either switching the rev counter position or else eliminating it altogether and opting for a brushed aluminium type one which is placed on top of the dash.

Im just taking down some notes on this since its a bit far away, but If decided upon (like the OMP pedals)I would buy stuff for it and put it in a corner.

I also like for example carrera rsr's steering wheel and gear lever cover which seem to be covered in some sort of material which looks quite good.

If you remove all the sound deadening crap that is under the carpet, the carpet itself adds very little weight. I can even get a thinner lightweight carpet kit from Classic 9. I think some form of floor covering in the main cockpit, and some basic door cards are in order. The other thing that would make sense would be to add some "track pads" to the foot wells, which have both form & function: they look cool, and they are designed to help prevent foot slippage. At some point, I may add some to my interior, but it's not a high priority at the moment, and can easily be added later when time & budget allow.

I'll post some pix shortly of what I'm doing with the Club Sport...but to describe it, it has both pieces of the stock carpet in the passenger well, but I've removed the rear seats, the rear quarter liners, and everything in the hatch area (carpet, sound deadener, etc). I also removed the entire head liner, but mainly because it was torn and looked terrible. With everything out of the interior, I then painted the entire interior with SEM Trim Black. For final install, I've re-installed the upper header piece (where the dome light is), and also installed the side header pieces from a 924S (the early cars don't have these pieces). While they are a tiny bit of added weight that an all-out racer would spurn, I wanted my car to have just a touch of refinement in the cockpit, and I thought putting these pieces in was just the right touch. I've eliminated the sun visor clips and the sun visors in favor of a "deep" vinyl shade that will be applied directly to the windshield. I also have one that I will put at the top of the rear hatch.

Back to the rear seat & hatch area: A flat or satin black like SEM Trim Black will hide a LOT of sins (as the saying goes). I toyed with the idea of developing a rear-seat delete kit, but once the seat wells were painted black, I decided it was just unnecessary expense and complication...but I may still have the guys at Classic 9 make something for me eventually. For now, I'm really liking the flat black interior and the spartan look. I may change my mind when I get it on the road and hear the road noise!!!

The one worry I have is that with it being black, it may get hot on sunny days. In my case, I'm trying to find that balance between form & function...i.e. I'm willing to sacrifice a little bit of heat gain in order for it to look badass.

RS style 924 door cards is the way to go Dan



I have a spare pair of Porsche scripted door cards which are water damaged to have a go at this modification at some time.

On max. my original project, I removed all the extra sound deadening stuff etc from it except from the centre shaft inner tunnel(dont know why I left it there yet), yes it does look badass-

I would be interested to look at your interior of the club sport ideola. Im sure a few ideas would be aquired.

While thinking about the interior, I tend to stare in the air as we say here, my wife thinks somethings wrong with me medically (oops).

I will eventually take some pics if I mock up anything for other members to look and have ideas.

From my Club Sport thread. Bear in mind, the carpet piece for the rear foot well area will be re-installed. But these pix will illustrate what I described above. Everything in the back is a bit dusty, but when I wipe it down, the flat black hides all of the imperfections quite nicely.

This might be a stupid question but since you have it installed you will know. Will that bar withstand a roll-over , as it is, do you think it would need flat plates to withstand a roll-over.

It looks as if it might go thru the local ICC regulations which states that at least a roll over bar which protects the drivers head must be fitted.

AH yes your interior looks very similar to MAX's interior, I can even note that you also didnt remove the sound deadening fromt the centre tunnel as I did.

That bar though gives it a different racy look. I think I would start putting a list together on my notebook for the interior .

BTW you mentioned track pads which im not sure what you meant by, can you elaborate on what these look like, are they like chequered plates which attache on the inner firewall side? Iv seen these somewhere and like them too.

Since the bar is attached to the C-pillars and the very strong, reinforced section where the lower seatbelts attach, I would expect it to provide some rollover protection...but it was never intended to take the place of a full cage. What it will do is add some stiffness to the rear of the car, and also provide mounting points for the six point harnesses I will be using. Since the car is intended to be a "club racer", I did not want a full cage in it due to cost and ease of ingress / exit. The bar I selected is a compromise between the simple harness bars that bolt to the less-strong B-pillar points, and the half-cage that went into the 968 and 937GTS club racers.

RE: the deadening material on the tunnel, I left it there out of laziness: the few extra pounds of weight reduction were not worth the mess and effort required to remove it. The UWB project is a different story...

RE: track mats, this is what I had in mind:
