Hey guys, I just had a question. I have a staggerd setup on my tires because I got them used at the time I bought my rims. I only did this because thats all that was available at the time and the guy gave me the tires for free. 235 in the front and 275 rear. I know it's a really big diff. My question is, I might be going to streets of willow this Nov. and because I don't want to understeer, would it fix or help at all if I just bout a rear sway? I don't have an after market swaybar right now, but I was thinking about buying the H&R rear sway. If not then would it just be best for me to get new tires, 255 all around?

 

don't know all that much about autocross or tracking. but if you are suffering from understeer, a stiffer rear sway would give you even more understeer. you'll need a front.

it would be best to go with same tire size all around if you can.

 

Not quite right, stiffening up the rear will probably help his situation by giving oversteer. Generally, stiffer = less grip on that end of the car.

Yes, that's what I suggest as well. If you can't change them, you can also try playing with your tire pressures to help balance it out.

 

ahh my bad. haha. at least i got one of two right.

 

The understeer you have now is caused by the staggered tire setup. Buy the new 255 tires. Don't try to fix the original problem by making changes in a different place to correct for it.
The wide rear tires are useful for 2 reasons. First for looks. And second for if you significantly increased the HP of your engine and needed the traction. Now you want to track the car, you need a symmetrical setup.
Are your wheel widths equal front/rear or are they staggered also?

 

absoulutely correct alnielsen. Buy the same size tires, your dsc and tcs and abs will be all the more happy also. not only that with the same size tires you can rotate them. i also would not advise a bigger size than a 245 if you are running 8" rims. Others run wider than that but I like the sidewall support theory.

I think there is one cactch here, though. If he has 235 f and 275 r, they may not be the same width wheels? If so, will going 255 f and r really balance out the car that much? I think it will help, but he will not return the car to being neutral again.

 

I agree, thats why the last thing I typed was to question about the width of his wheels. At this point I have to assume they are the same width. If they are staggered, then it would probably be cheapest to by a new rear bar. That wouldn't be the best answer, it would be the cheapest to cut down on understeer.

 

D'oh, sorry Al. Completely missed that last line.

 

They're staggerd as well, I have 8 1/2 front and 9 1/2 rear. I think thre best bet for me might be to just slap on my Stock wheels and get 245 all around, am I right guys?

 

For just track duty, that sounds like a plan. As was listed in another thread, Tire Rack is running specials on Kumhos right now, and the MX are pretty good inexpensive high performance tires.

 

Why all the tire suggestions?

He said UDERsteer, maybe just lactose intolerant?

yeah... Everytime I see the thread title, I think that it's about a bovine problem. Something with misspelled udders and steers.

 

OMG!!! Thanks guys, I didn't see that typo untill I looked closer. UDER

 

Hell, don't woory about it.

It's your first time on the track.

Just drive and have fun.

 

If it is your first time, I suggest you to do a wheel alignment and have fun. Slow in fast out.

 

I have actually been on the track a few times, but the car was stock. I wanted to know the diffrance on how my car would handel stock vs. it being modded. I love the track and I can't get enough of it, the only real problem I have is getting my gf off my case. She thinks it's unsafe and I can get hurt, I told her better then me doing in on the streets. The funny thing is, I thought most gf don't like it because modding and takeing your car to the track is a waste of money. I just wish she would go and see how safe it is, but thats a diff. subject.

 

If you're doing lots of track days, why not put some R compounds on your stock wheels and use those on the track?

 

As "safe" as it is, you always run the risk of this happening

I was actually looking for some good slicks yesterday. you're right, I was thinking about putting on my stock wheels and doing that.

 

Outch.

 

Pat Olsen makes it into another thread on the internet.

Thats a legacy at a Porsche club hpde.

 

At least he wasn't seventh.
