As some of you may know I purchased a set of Fikse FM5s from a fellow board member, but they are not an Fbody offset. Here are the specs again.

17x9.5
BS 7 3/8"
Center line is 5.1875

17x11
BS 8 3/8"
Center line is 5.9375

My results are

17x9.5 55.5625 or 56mm
17x11 61.9125 or 62mm

From this imformation they where able to tell me that they are a C4 offset.

I had a sell pending on a corvette forum, but fell through. I decided to look to see what if anything I can do to make them fit properly. I jacked her up last night to see how far off it was. I mounted just the rear rim and it hit the bump stop just short of seating properly on the hub. Can anyone help me out? Thanks alot in advance.

did you jack it up by the rear or by the body?

I would think you'd have to run spacers on the rear. I had 17x11 +50 on the back of my TA and I didn't think they rubbed, but after I pulled them off I realized that they definitely did and obviously with a +62 they really won't work. Get yourself some longer studs and some spacers. The fronts will work.

I bought my wheels used and they have a C4 offset also. I had to use a small spacer on the fronts and the rears fit without any issues. Like David asked did you jack up the rear by the rearend or by the body? If you did it by the body it will hit the bumpstops.

Yeah I did by the body. You are saying I should jack it up by the rear? Also DopFedZ what is the offset of yours? Danny from Fikse and XstaZ28 both said they where from a C4 vette. SO a spacer is need for the rear?

the body will be in the way of any normal 11" rim if you jack up by the body

some bend the bump stop back some.. some cut them off. the bump stop normally rides kinda inside the wheel, of course it is ideal if it could never hit the wheel or tire ever.

I will try and mount a wheel this wekend jacking up the rear. I had TT IIs on another TA and I know what you are saying about the bumpstop riding in the wheels so to speak.

According to the ebay link when I purchaed them they were 56 fronts and 50 rears. The guy told me he had them on his C4.

I only needed a spacer for the fronts. The "mounting hub" of the front wheels were touching my the caliper bracket by a bit. Instead of grinding the bracket I already had extended wheel studs on the fronts so I decided to run a small spacer.

Those are the same exact offsets I had and the 50's still rubbed. That +62 is still gonna rub.

How much are wheel spacers typically? I have Fikse's with the correct FBody offset but will need spacers if I convert to a C5 brake setup.
