Are wheelspacers needed to run 225-45-17's on stock SVT wheels ? I run G stock on RS2's and get beat bad by a Mini on NTO1's.

steve35svt, I moved your post to a brand new thread.
The other thread you posted in (The Who's Who of Focus Autocrossers) is not open for this type of discussion.

Now, on to your question... [;)]
No, you won't want to use spacers at all.
That would only worsen the chances of rubbing on the fenders, as spacers push the wheel/tire further out towards the edge of the fender.

I ran a couple sets of RT-615s in that size with success, but they are a tight fit.
See here:

I would recommend running a 215/40/17 R compound if you really want to be competitive.
The shorter sidewall will help in turn-in response, and the shorter diameter will help you get out of the hole faster.

Now, if you really want to see why I don't run the 225/45's anymore for AutoCrossing, read on:

Who makes a true R compound in a 215/40/17? I've competed with this car two years and like the way it handles for a front drive,previous racer was C prepared Trans-Am.The only thing I miss is TORQUE!

I didn't think about the limited suppliers for that size, but there is at least one.

If you're on a budget, the Nitto NT-01 has been working pretty good for the people running it around here, though you'd have to opt for 215/45 again...

Now, here's something you'll really like.
Hoosier A6 in a 225/40/17. Extra width and 1/2" shorter than stockers. [;)]
This is a GREAT tire!

Great,225/40's fit ! I was concerned by the lack of clearance between the rear shock and the tire.Yes I'm on a tight budget , 4 kids will do that , and NTO1's won't beat that Mini. I've bought used Hooier's from Appalachian Race Tire before in the late 1990's ' I'll have to check if they still offer them. thanks for the help!

R-compounds are great. for WeeAsp would you mind sharing tire pressures?i've tried both higher and lower in the rear tires and prefer lower pressures for more controlled brake-away.

Ooof....

Tough question to answer because I tend to start with a baseline of 32 PSI front and rear and adjust based on the course.

Of course, sometimes, I can tell based on the layout if I am going to need more lateral grip (increase PSI on all 4) or more rotation (increase PSI rear only).

That said, I would not go below 30 PSI in the front or any higher than 36 in the rear.

thanks alot ,if i can convince the mrs. race tires are budget worthy ,that will be a good starting place.having competed in rear drive for years and less than 20 events front drive,i'm still figuring it out.your starting pressures lead me to believe the SVTF is better balenced than i give it credit for.

I have 225/45s on SVT wheels and they scrub on hard dips. I can barely fit my fingers between them and the fender(I'm sitting on the Eibach Pro Kit), so I would hate to think what happens if I were to try auto x with those...probably eat a notch in my fender.

You will rub with a 45 series tire.

I run a 225 FORTY (40) R17
