offset versus scrub radius Options

[r_towle]

Does it make a difference what the offset is on a wheel with regards to scrub radius?

It does not seem that it would, given the stock suspension, no custom struts etc.

Aside from that, what is the reason (aside from cost and availability) for using large spacers versus getting wheels that mount up with no spacer, yet are wide for flared cars?

One is limited by the 914s front suspension. The most backspace I could phisically get on the car was 5 inches. That does not prevent an increase of wheel width.
I ran an odd set up of 8 wide (Porsche stock backspace) inch with cantis & 10 inch straight side silcks/wheels (5 inch backspace) in back. Not an ideal set-up but good enough for SCCA NTs in EM or XP.....twice as many wins as losses & free tires are gud.(IMG:style_emoticons/default/biggrin.gif)

The 8 inch fronts increased the SR about 1.25 inches over stock. Apparently that was not too much as I could still dial out push in the standard way. I do know that another inch will get ya. Oversteer is good at AX.

The front Hoosier R35 cantis were about 9.5 inch tread width and it is tough to get heat into the tire at AX with a light car (about 350 lbs per front wheel). Them first couple runs were ineresting tho.....I think tire tread width is kinda self-limiting.

All the BS that Brit is going thru with the car started because of the limitations of the 914s front suspension......there's a clue there. (IMG:style_emoticons/default/smile.gif)

I have seen other makes & models cars go thru this same problem.Those that cured it went pretty much the same way. Those that never did finish somewhere behind them.
