I am looking at the options available to move my wheels a little further out so as to "fill the guards" better. Around 3/4" at the rear & 1/2" at the front would do the job.
At the rear, I seem to have 4 choices :
- Get Simmons to rebuild the wheels with a 3/4" change in the off-set (huge $).
- A new chassis bracket for the lower a-arm that sets it all out 3/4" & a longer upper arm. (This would change the geometry, so I am not keen on this one).
- Just wind out the spherical joint adjustment as far as is sensible - but I'll probably only get about 1/2" with that.
- Use 3/4" wheel spacers - by far the simplest & cheapest.
At the front, I don't have much choice as the DRB uses an '87 Vette setup & the lower a-arms pivot in mountings well & truely welded into the chassis. So I figure that there are only 2 choices :
- Simmons wheel rebuild with 1/2" change in off-sets.
- 1/2" wheel spacers - again, simpler & much cheaper.
I have heard some conflicting stories about the safety of spacers, but suspect that they would be ok if they were machined accurately so that the circular locating lip on the hub mated exactly into the spacer, & the spacer had a matching lip which mated exactly into the wheel. Fixing the spacer to the wheel with c/s bolts would also probably be a good idea.
There is also the issue of whether longer studs are required, or if just longer lug-nuts are sufficient.
I would really appreciate any comments from the GT40 brotherhood.
Kind Regards,
