Turbo trailing arms or alum SC?
 

Is it worth it to convert to the turbo trailing arms for an 85% track car?
Anyone have experiance with results, before and after a turbo arm conversion?
Turbo control arm pluses, bigger wheel bearings, anti squat, less camber change during suspension travel, better rear bump.
But is it going to lower lap times?
thanks,

I think there's also the issue of the turbo arms relocating the wheels tires which usually requires flares. I think you can also accomplish some of the same stuff by changing the mounting of the stock style arms.

A while back I had the opportunity to buy a pair of 930 arms for cheap, and posted the same question. My recollection is that they make a marginal difference, and given the labor involved in swapping them, it doesn't make a whole lot of sense. You could probably find the thread with a search...
