Hi all

Car feels down right dangerous 130+ on the highway. Mods are in sig (hopefully)
-MT82
-15x10 MT ET Street R
-Whipple 751whp/595 TQ

Any similar experiences?
Anything that can be done or just nature of the beast on the street with bias ply?

Thx

Jeff

Do you have a bias fly front to match the rear? If not I 100% guarantee thats your problem right there.

In most cases you can get by if you have a radial skinny upfront. If you have a bias ply on the rear and a full size radial on the front It will be scary at high speeds. Sometimes if you run higher pressure in the rear it will help a little bit. However, general rule is front and rear tires should match.

4" is way too narrow for a 215/55 tire. 6" is min-recommended, and you might be able to get away with running on 5.5" for short drives over a short period of time. I wouldn't ever suggest going narrower than that for 215-wide tires in street driving no matter whether they were radial, bias, or bias-belted.
