Tire size

What size are you trying to run?

 

You could probably do it but it will bulge. Think old muscle car with wide bulging tire look, I'd imagine the softer sidewall would flex a lot.

 

I would recommend checking with the tire manufacturer.Usu 235 is best on a 7.5 " wheel but it varies.

 

Go find the tire you are looking at on www.tirerack.com. Click on the "spec" near the tire you are interested in and it will give you the recommended wheel width to mount that specific tire. You can also go directly to the manufacturer's website, i.e. Kuhmo or something and they will often give you the wheel width required. I know Hoosier does this for every tire size and style they have.

 

That sounds a little wide too me.

 

I looked at a random tire on tirerack.com, the Kuhmo MX and it recommended at least a 7.5" wheel for the 235 size.

 

Rota is the cheapiest you can go for the best cast wheel. I would just search "rota" in a whole bunch of boards. I can guarantee you will find some for a decent price.

 

I went from oversized tires to stock size and gained in the handling dept. With the oversized tires, they looked cool, and gave me lots of acceleration grip, but the roll from the larger than normal tires was alot worse than I thought.
getting the right size tire really showed me that.

besides, acceleration grip is the last thing these cars need.

 

16lbs. is really not that heavy for a cast wheel. You can easily get a 17x7.5 for that weight. I just like them because they are inexpensive, but 5zigen's are a great wheel also.

 

Attacks, check out my profile. I have a 16x8 and a 17x7.5 rota that both weigh 16lbs.

 

Oakos.com will compete with them. They are a good wheel. I have used them for close to two years and no warping or anything.

 

I recommend 17x8's though. You can easily put 245's on that size. Trust me.

 

245's do fit under the fender, but you can't change your stock understeer. So don't try to reduce the negative camber in the rear suspension if you do it, just warning you.

 

Understeer kind of sucks....

Q: I have Whitelines, 27 front and 24 rear.... if I bump the rear up to 26 will it take out some of the understeer. I got hella understeer in hard off throttle corners like woah!

 

^^Definitely dial some of the rear negative camber out. It helps a lot to cut it in half. I went from plowing every corner in autox to getting a nice controled oversteer by trailbraking.

 

^^Thats what I mean, you don't want to change it. OE negative camber will be the only way you can fit it underneath.

 

Wait. I have the "performance allignment" from SOG. Roughly -2 up front and -.8 in the rear... if I remember correctly. Do I actually need less now that I have the thicker sway in the rear?

I got the bigger front for more safety but I'd still like to be able to snap the rear a little sometimes with some off throttle. Right now the car just says no and understeers instead....

 

in my opinion, the best way to check if your car is running too much negative camber would be to go to a spirited drive and check if the tire temps are uniform across the tread... autoX would be a nice controlled and safe way to do this... i know tire pressures are in your target range before you do it though

 

I have never really been able to get that much throttle oversteer except in the wet. What I have noticed, is being able to control the oversteer during trailbraking. If you tap the brake midway into the corner, it normally allows the car to rotate depending on how much force you apply. If you slam the break, you will spin out. This only works if you aren't already understeering though. Best way to get out of understeer is to counter steer briefly when it starts to happen.

 

Nice tips.

I just remember that the rear end would step out a lil easier with the stock setup. And it's not that I want my AWD car to act like an FR.

I got an appointment to get some more SS tuning so I'm sure he'll notice if there's anything abnormal.
