This just in for Jim.

Picked up the car this morning with new Falken RT 615's on all 4 corners. Stock rims, 275/35 R18.

Nope. RT-615's run small....no rubbing. They are smaller than stock heigh too, so I assume I could lower with no issues as well.

Sweet. Keep us updated. You may be a bit wide for the rims you're running but at least you're balanced...

You of all people most definately have to know that I am certifiably unbalanced.

We ran with a big rear sway bar and stock front on the T2 race car. We had Hoosier A6 275 on 18x9.5 F/R both. This was knife edge neutral, I liked it, I wouldn't recommend it for anyone short of expert skill level. However, with a 245/275 split it would be without a doubt the way to go.

What do you mean by knife edge neutral? And why wouldn't you generally recommend it?

How did you fit the 9.5 rims, especially with 275 slicks, on the front?

Probably installed flares on the body and pushed the hub out.

There isn't a real easy way to run 9.5" rims on the front. The back is a challenge enough, to say nothing about the front. I'm guessing he just pushed the entire hub out and went from there

Not sure if they were allowed to in their class or not, but you can tell he's not running any flares in his avatar.

I know it's not easy to run 9.5s. And, as mentioned above, especially since he's running 275 Hoosiers, which are gonna be even wider than our normal street 275s. S'why I'm curious as to how he's running the 9.5s up front.

They fit with a baseball bat doing a ton of work on the inside of the fender flanges.

I wouldn't recommend it since it is VERY hard to control without spinning out. Very easy to rotate = very easy to rotate too much.
Bobby gave me a contact to look into adjustable rear sway bars. I'll look into that soon...

With the ground control kit you could try the same basic idea by using spring rates, instead of 500/550 you could try either softer up front like 475/550 or stiffer in the rear like 500/600. I'm sure coil over springs are cheaper than a sway bar also.

True, but an adjustable rear sway bar would be easier to fine tune. I have ordered 650/700 Hyperco springs to replace my 500/550...
