Maybe you could try the 19mm 3 way adjustable m030 bar. Just to get that balance right. Its inexpensive to buy from the porsche center over here...

That's some nice driving Vaughn, very impressive. Makes me nervous just wathcing it, which is probably a good sign that I should never get on a track! That track is so narrow I can't even see where I would try to pass, probably another good clue that I am not a race car driver deep down.

That looks like a fun track. . .but there looks to be one spot where a loss of control could send you into incoming traffic on another part of the course! Shouldn't there be a barrier there??

Yes, actually I do have the M030 19mm rear Cup Car bar, and do like it - it was pretty cheap, $142USD when I got it (with bushings) new and of course original part quality...

If you are having trouble with understeer, try a little more rake on the car. Set up properly, the 24 should be dead neutral unless you just throw it at the scenery!! Lots of people make the mistake of messing about with sway bars and dampers before the balance of the car is properly set up. Do you know your corner weights? Whats the front/rear balance of your car?
Once i got mine dialled in fairly well, the handling was fantastic. Still a bit of fine tuning to do, but she's 90% there.

Hey folks,

a little comment from my sight, in the UK,germany e.g the succesfull drivers using the convertible for racing!! The weight is of course higher but the body is much stiffer so it s more stable in cornering.

By the way, were does LOL stands for ? Or,what is a Kudo?

Oh Man! I had my pooch on my lap as I was watching that and he yelped 'cause I was squeezing him too hard as you were almost overtaking him in the corner! What a blast! Where I live, that's called "morning commute".

I haven't read all the comments up to now but it looks like he was off his apexes a bit on some of those corners.

Hope you can post more of the videos you get. Maybe you should start a new website: "Vicarious Racing".

Good luck!

LOL = Laughing Out Loud or Lots Of Laughs


There's also ROTFLMAO! Rolling On The Floor...

Steve - you're quite right, and I am running a bit tail-heavy, which is part of it too. It's 48/52%, and a little low in the rear, and that may be one of the things we do to balance it out. I don't remember it being quite like that earlier on, but then again I was 5-10 seconds slower a lap! Anyway, always plenty to adjust, and every time you get faster, you have to completely adjust the car again since what worked OK for a 1:21 lap feels like crap at 1:19.5!

Vaughan,

48-52 front to rear? I would advise reversing that so it's 52-48. Reason i say this is the company who did my baseline chassis setup run the Porsche cars GB GT3. Many years ago they won a bucket of trophiesand championships in guess what?? A 931. They admit that due to the regs of the day their cars were not as developed as mine, but the basic chassis dynamics are the same.
Ultimately, it's always a trade off. Also, 3.5deg of camber all round seems to be the best, unless slicks are being used. If you set the balance by adding a tad of +ve rake into the car, and perhaps a smidge more castor, as rake effectively reduces castor a bit, you should be able to banish the understeer.
Nice to see a 24 racing propely. Simsport and myself are in a handful of guy's over here using the 24. Most plump for a 911, but i do think the 24 is a better circuit car.

Good Luck,

Steve

Well, I'd at least like it at 50/50. It's doable, as long as I can still get the rear adjusted in spec for camber (sometimes a struggle on my car). Good point about minding the caster, though. Right now I don't have much more than stock (around 4-4.5 deg), but can dial in more if I want to - just a bit of wrenching to juggle a bunch of camber adjustments around.

I'd love to hear if they have any recommendations on just how much castor is best for the chassis; I think I can get it up to 6 or more if desired.

Not sure I want that much camber; while I do keep it pretty even front/rear, our tires (Hoosier road race radial R6's) don't seem to like more than 3 on this car, maybe 3.25, but haven't made it happy with 3.5 yet. I think they're over their desired working point then. Does help that my car's so stiff and low.

Cheers!

That looks like a hell of a lot of fun, and I like the vengeful laugh at the end of it. The Porsche could obviously out pace the Beemer on an empty track. The weight distribution is the key, and you are kicking ass.
BMW is a wierd company, dont you think? Who else would make a 400 horsepower 4-door sedan that looks like a Ford Taurus?
