Here is a pic to give you an idea of the fender clearance.
After the swap is comepletely done, all I am doing for a long while is alignment, installing my performance parts and new paint job. Then I just want to enjoy and learn the car for a while.
BTW: This tire combo is much larger than a 185 rolling dia. but not all that much larger than the st205s. So compared to a 205, the performance should be decent. Plus I have some nice things to really up the power very soon.

25mm spacer on the rear, none on the front.
I had a 8mm on the front, but could not get it to bolt down tight enough. It still fit though. I will most likely install the space when I get some longer front studs.
