Going to the track this weekend, so I'm going to try a few things.

Thanks

I find that a front diff with light oil helps reduce tire scrub in sweepers. I've used anything from 10K to 50K depending on traction levels. With the low horsepower, anything you can do to reduce scrubbing will help. Zero toe-in all around, for the same reason. Both of these items will be even more important to reduce tire wear on asphalt.

You may need a heavier rear (or lighter front) sway bar to reduce understeer created by the wide rear tires.

The following is for HPI tires:

I use less camber overall for VTA versus USGT and TC; the VTA tires are both wide and unbelted, so while cornering the outside tire tends to form a cone shape with the larger diameter toward the inside. My settings are generally -0.5 to +0.5 (yes, positive camber) depending on traction levels and age of the tire (older ones deform more while cornering).

The Protoform tires are stiffer, so the camber settings will likely be more negative than those for HPI.

Howard - thank you for the great response, that makes a lot of sense and confirms my thoughts. My plan was to reduce camber this weekend ( currently at 2 degrees on PF tires ) and now I'll also work on my toe settings.

It's a fun class because of the new challenges - 1st time out I had a big smile every run.

I have 3 brand new never ran pairs. One mounted and glued, one mounted and unglued, and one never opened. I also have 2 pairs mounted and glued in used but great shape. I also have 4 mounted and glued but never used rear hpi tires.

Carl's stuff is really cool, as it ANYTHING you get from MCIRacing

I did my own stuff, but it's printed vinyl, and/or cut vinyl (vs sticker)

I LOVE Gary's COUGAR body -- doesn't work quite as well to me compared to his FIREBIRD bit it's a FoMoCo so it WINS in my books...

I did a few of the original ones, but I think you made some changes if I recall.

We ran the Mustang in the OUTLAW Enduro's on Mike Sheehan's cars at Cal-Raceway too.

Have anybody tried the Kyosho 1970 Chevelle SS 454 or the 1970 charger bodies yet. They look real good.

I've run it a few times, great looking body, very tough.

Obviously , you don't need to attach the included plastic bumpers, I just painted them in.
