Ron, thank you getting this thread out of the toilet and back into some really good discussion. :D I might need to "rent" you to come fix my disaster of a build thread....
As others have said, I enjoy and appreciate the wealth of info you're sharing. :thumbsup:

Flash I think you've done more to accomplish that than anyone by staying off the thread recently.:lmao:

Wow Rob, I go away for a couple of weeks and the car has come together quite a lot! Looks good.
The tire/wheel info was way too much for this early in the morning but glad it is there to re-read. Thanks.

Thanks I'm making progress and have some more things in the works that I'll be posting on in a few weeks.

When a car has significantly more front weight distribution … say 53-56% … the front naturally wants to roll more than the rear. Having the front track width a little wider helps balance the car’s roll angle. I don’t like to have the front TW more than 1” wider than the rear, on the roll angle balance goes the other direction & the car wants to roll over on the outside rear tire too much.
With the much wider rear tires moving the rear TW "in" ... I suspect your rear track width is substantially narrower than your front & will contribute to things that cause a push condition. You should measure both front & rear track widths & post the info. If the rear is more than 1” narrower than the front … and if you care about this … then you would want to narrow the FTW, or widen the RTW or a balance of both.
In case this is new to anyone, Wider front TW than rear = tightens the car … too much makes it push. Wider rear TW than front = frees the car … too much makes it loose. If the car has more rear weight, I may, or may not, run the rear wider than the front. It does depend on if the suspension travel strategy is “high roll/low pitch” or “low roll/high pitch”.

Ron flew the coop for a week so until he gets back I'm taking a break from the tire/handling discussion. I have some more info on track width and such to throw out there for discussion.:sieg:
I did take track width into consideration when choosing the tire wheel package. My front comes in at 55.25" and the rear at 58" Ron was surprised by this since it is intuitive to think tubbing in the rear would push the track width in significantly. I had to remind him what you all know. My car has a big but. :lmao: So more tire to the inside of the fender would have widened the gap in front to rear track. Currently I have 1.75" more TW in the rear which should help free the back end up some even with the 345s.
I don't think I ever see anyone post about it. What is the typical TW measurement on a first gen Camaro? |
