245/40's, no rubbing, no rolling, no bending. A few more pics........

 

that $hit is tucked! nice!!!

 

and no mo money cuz cpo35s are expensive hahahaha, and are also custom made god forbid you bend one :\

 

The last picture where Silencer is picking up the inside wheel. You may want to reduce your rear sway bar setting or increase your spring rate all the way around. You will get better times. Also, you should be able to fit 265 without any mods as well. More rubber means more traction.

 

mmm with 265 he will have to roll the rear fenders.

also i don't know how possible it is to not tripod on an autocross course. i'd say hte stock swaybar in the rear is soft... and i'd say the stock suspension is soft compared to what i have now. and i tripodded in many instances on my local autocross courses. it's just something that we have to deal with, until pnumatic suspension.

 

Hmmm...What rate springs are you running? Are you running a larger then stock front bar? Is your suspension corner balanced? Did you lower your car with additional rake in the front or is it level? You can eliminate the tripodding effect through changes stated in the previous four questions.

 

front bar is stock, suspension is muellerized, so yes corner balanced and a lil lower, and yes hte car is more level now.

btw... wouldn't decreasing overall suspension stiffness make more tripodding occur. fully stiff suspensions with enough travel like in grand touring cars don't tripod too much. but then again they also don't do short radius cornering like in autocross.

 

Correct, increasing the spring rate is the way to go. A larger adjustable front bar will improve your handling as well. The problem is not enough spring rate and too much bar in the rear, which causes it to lift in short radius turns.

 

welp i'm betting he drives home from the cone lot so sway bars make it easy on the ***.

 

I run in STU which limits me to a 245 tire. The rear 25mm bar is at it's softest of 3 settings. I'll just say that I'm already between 600-800 lbs f/r spring rate, but I do plan on increasing the front. I'll be testing 3 different front springs with 50 lb increments when the weather cooperates. I will also be trying 3 more front/rear ride height settings. The tire of choice, Falken 615's at the moment and possibly switching to Yoko Neova's on a 17" wheel. Test, test, test.

Back on topic, I have zero roll by stretching the 245 tire on a 9.5 wheel. I've run as little as 28 lbs with no ill effect, at least on the 615's. The Kumho MX has a softer sidewall in the 245/40/18, but still a very good, predictable tire. I have also run the rear ride height low enough for the rim itself to be tucked in the wheel well at rest (-1.8 camber). Still no rubbing.

sexy sexy wheels.... mmmmm.... me want.....

details please...

n

 

haha i already gave the details. those are custom specced (only way to get them anyway) racing hart cpo35 (same wheel in i believe 10" on kj's car wearing 305 hoosiers). only way to get them is to talk to racing hart. they discontinued the mass market cp035s and now only do them in custom sizing specifications.

 

and I just bought my wife a GSX....what kinda $$$ ballpark we are talking here... damn, need an aem too.

it will never end.

silencer, how are the wheels looking on the inside, any rubbing? what kind of suspension you got?

n

 

mmm they prolly run the same price as a set of volks... and are definitely the same quality and definitely the same weight class. however they come in whatever size you want, you just can't get spares so easily.

if you get the 18x9.5 +35 it would all depend on the tire you run. as you can see he's running a skinny tire stretched so i doubt he has any problems as the actual wheel is prolly the limiting factor there, cuz the stretchedness is moving him away from liners and control arms.

if you wanna run the 275 285 you will likely encounter some control arm rub, you did say before that your liners are intact so you might get away with no liner rub. the reason i say this is because your turning moment arm was pretty large with all that spacing, so the turning moment you lose with having an effective +35 offset as opposed to 20 and the extra distance you gain while being that much closer should make up and even out. however i would bet on a lil control arm rub czu that's what mueller tells me when he runs the 18x9.5 fn01rcs and 275s.

 

We've got a couple guys on the 18x9.5 FN01RC's with 285 V710's, no rubbing on the rear trailing arm.

Haven't checked full lock in the front though.
