I agree.... without the right tires, you're muzzling up that Mad Dog Motor ! (Proof is running in the 8's, when your mph indicates a low 7 second et capability) Bias ply fronts are to match the rear bias play slicks so many run with, hence better tracking. I believe all MT ET Fronts are bias ply, which is what I run right now. (Maybe they have radial fronts now, not sure).... but back years ago, I wanted to try radial skinny fronts and found a tire that would go on a 15" rim, 4.5" wide that would stand 26" tall. It was actually a tire designed for volkswagons and was dirt cheap.($ 29 a tire if I remember right) They worked well, but bear in mind, that radial was heavier than the bias ply and it showed up on the timeslip with a difference in the 3-4 hundredths area vs the MT ET front. Hence, basically almost chopping in half the benefit of the front skinnie on my set-up, which typically gives around a tenth gain on my car, give or take a hundredths or two. I agree with those who say you shouldn't mix radial and bias-ply, but I'll also say, for a C4 corvette at our street/strip speeds.(Typically under 130 mph), its fine. My car tracked fine regardless of if I had radials on the front and bias ply on the back or vise-versa. Lots of people do it. However, I will correct myself in giving the advise I did earlier.... with a heavy A-body, I can imagine its different at speed than our stable C4's.... so perhaps he shouldn't as jonszr1 eluded to earlier. I don't know. As a note, there is nothing wrong with Bias Ply slicks at 100 mph or faster.... they grow and you go down the track, with no real stablity issues. Problem lies in when you try to make turns, especially fast ones..... you'll get a lot of sidewall roll. |
