WTB - Texas - One 8.5" M68 Wheel (Rear)

Guys if any of you is in Texas, preferably 150 miles around Houston, and have the stock style 68 wheels on-hand, please reply.

Need: One 8.5" style 68 wheel.


_______________________
Story: Previous owner installed a square setup with 8.5" upfront. I want to replace this with the thinner wheel up front to improve control. Also rim is bent so need to replace anyway.

I found one really clean 7.5 wheel off of craigslist, so that helped. Another will help me close the chase.

And then YoItsMac did the successful argument for square setup!

Why do you say staggard would improve control? I'd argue square would increase control on a 50/50 balanced car. I'm on staggard M68's and I wish I was square

I love a square setup with all 8.5 wheels for sure. Atleast from my experience with my current car, it is more likely to oversteer (who doesnt enjoy oversteer). Coupled with suspension refresh and a sport tuned alignment, it has definitely been fun to drive so far.

However the move to a 7.5 up front is more driven by a curiosity than a science-backed analysis. Reading forums (very anecdotal) I felt that a narrower and lighter tire upfront will put less load on the front suspension. With control arms and shocks/struts better able to place the tires onto the ground - maybe, just maybe I could be more stable both in straight line and in curves.

Once again this move from 8.5" to 7.5" upfront is a test of hypothesis, and hope I could provide y'all results of this move once done.

Meanwhile I really need a wheel to replace my current one. So even a 8.5" 68 is welcome.

Sorry man, don't mean to thread jack, I definitely think you should look for a replacement 8.5

I just got my 68 unbent (and then balanced) for $125 at a rim repair shop. I don't know if you've weighed this option. It may make more sense to you. If you pick up another used one, it could be misbalanced, have a mismatching tire (which would cost you more) or even another bend! (the one's I bought from a member was bent on three wheels) Something to keep in mind...
Alternatively my local recyclers sell 68's for $150 a pop (another option for you)

The difference in weight between the 7.5 and 8.5 is about .92lbs, or just shy of 5%. For 5% weight reduction, you lose 8.8% of your footprint on the road. If you want to lose some weight reduction in each corner, you could lose more weight by choosing lighter tires.

If you want better straight line stability, PM me..I can get you there for $100

Again, sorry to go all nerd on you, but I'm just trying to save you money and potentially some headaches. I personally was disappointed and wish it was cost effective for me to switch back to square.

TM!

I think this could be the most valuable suggestion of the thread.. Thanks for the thread jack!

Your points make sense and have successfully convinced me to stay with square. Changing thread title and WTB.

(I am curious on what you did for $100 for improving straight line stability though, in addition to shocks/struts/control arms/balancing/ alignment)
