I know this has been brought up many times before. I have a bone stock 02 996tt. I want some stickier tires then my street PZero / Stock size. I know that at least one person here has said not to go with sticky tires with stock suspension. I guess he is saying these cars will roll too much. I was going to use Toyo RA-1s, but I run these on my 914-6. (For Sale BTW, shameless plug) I'm no newbie to track driving. I'm an instructor with NASA/PCA. OK...to the question. Does anyone have any experience with Nitto T1R? It's listed as a high performance street tire. So are the PZero tires, but they suck pretty bad when they are half way pushed.
Any thoughts?

 

I haven't tried any competition tire yet,i'm buying Toyo 888R it's been highly recomended because it has the right size for 18 wheel's car and are at good price,last longer then MPSC , have very good grip and are not bad at wet.

I've been told that the RA1 has better grip then the 888R,but not right size for 18 wheels.

 

I've used both the Toyo 888's and the NT01's from Nitto. Both tires are R compounds and have superior grip to the PS2's, but shorter lifespan than the PS2's.

 

Can't say enough good about R888s. Great grip, surprizingly good in rain, surprisingly long life. Lasted longer than my last set ps2s! They are a little noisy though.

 

OK...what about this part of my question? "I know that at least one person here has said not to go with sticky tires with stock suspension."

 

You'll be fine with a DOT treaded R-compound. R888, NT-01, MPSC etc. In fact you can get by with stickier, but you will destroy your rubber bushings which are everywhere, especially on tight twisty circuits. In fact, you will destroy them eventually anyways, so just keep an eye on them. The transmission mount is probably the most likely to fail, but it won't cause much if any damage. Also check the rear suspension thoroughly every few events to make sure everything is sturdy. I had something else fail in the rear suspension but I can't remember what it was. And that was with JIC's.

Most street cars roll a lot, the Turbo is no different, but eventually you will want to upgrade to a coilover and rear sway. But you'll be fine until then as long as then isn't many years of track days later.

 

recommendations on tires other than r compound or PS 2s. In GT 2 sizes.

 

with the Toya R888's ...on an 18" wheel, & lowered suspension do you guys go with a 335 in the back or a 315? and if the 335, do rolled fenders do the trick? or do you need more work to the fenders?

 

315's are less headache and less sidewall. The Turbo has enough slop from rubber already, adding more slop with huge sidewalls isn't going to help IMO. I go for lowest sidewall possible for more road feel. But I like a more raw feel, even on the street.

 

Is anyone running Hoosier r6 on oem whls? What sizes are you running f/r. I've ordered a set of 245/35 and 295/30 for overall diameter to be similar. Anyone else running these sizes in combo? Hard to find a narrower tire in front (used 1 cycle). Better to have a wider rear tire for 245 front? These will be for de events on unmod 03 turbo. Tks. And despite doing a search cannot seem to find exact answer...

 

I've run them on OEM wheels before, you can run the 245/40 (not 245/35) and 315 rear which is what I ran and plan to run in the future (A6). That's the easiest setup and works on stock wheels

 

What would be the aspect of the rear tires? 30? Thanks!

 

Yes, they should 30s

 

1) With a 315 rear do you need to roll the fenders with stock wheels?

2) What offsets can you use without rolling the fenders using 315 rears?

 

There is no reason not to roll your fenders. Just do it. If your ride height is lowered and you're trying to run these really sticky tires you have no business doing it with a knife edge pointed at your tires, it's a safety hazzard.
