Widening Track The Correct (But Affordable) Way?
 

My 986 S is a toy, not being kept all original, it's got minor body damage on both rear quarters and some other cosmetic issues. I'm likely going to go wide body with it using rear fender flares and a 996 GT3-R style front end.

I enjoy taking my 986 to the track for lapping days, I'm trying to maintain good suspension geometry while running significantly wider and lower offset wheels.

I've seen control arms from Tarrett and other companies, I've seen axle spacers, and a few other things.

I'm trying to meet somewhere in the middle with maintaining good handling performance without spending $10k relocating suspension mounting points and basically re-engineering everything. What's the most affordable way to increase track width without sacrificing suspension geometry too badly?

Thanks!

I have 15mm spacers up front, 25mm in rear, with godspeed coilovers lowered to the middle of row sport spec range. I was able to Max camber out up front (barely) and rear (with a bit more room to spare) within factory specs. That was 2 years ago and I have not had any undue suspension wear since then. So, you can go at least that wide without problem. If I raised it back up to USA spec height I could probably put 25mm spacers up front and run square with 245s all around without problem.

If you do start running square, be aware that this will change your steering dramatically. When I went from 205 to 225 it took almost all the understeer out of the car so going square would likely introduce oversteer. Not what you were asking, just wanted to share.

Just keep in mind that by using spacers that are too wide you will be taxing the bearings and will have to replace them sooner..

You are absolutely right. Interestingly, Porsche offered factory 19mm spacers in the rear. That's one of the things that influenced my size choices.
