Slicks are made to stick. When they stick they will find your weak point or points.

I remember the first time i put slicks on my 04 Cobra. Ripped every pulley off the motor when I launched it. You ever seen that happen?

What would cause that? I switched to slicks and snapped lug studs and could see how rotational parts break but pulleys?

I don't know. I guess going from no load to instantly a ton of load on the motor probably broke one pulley and the rest followed suit then the shit hit the fan. I'm sure the belt when crazy for a minute and the rest is history. If I remember correctly, it appeared that maybe the tensioner broke first.

I ran 4.30's for about 2 weeks and went back to a 3.90. Gained zero with the 30's. And couldn't make it through the 1/4.

I ran the stock irs with a brace, but i didnt launch it that hard. I think best 1.8 60ft. Im swapping a built solid in now so i wont worry as much. Ive heard from many cobra/irs guys that slicks are actually safer than drag radials because the sidewall abosorbs the initial hurting better than radials. Also slicks are less likely to wheel hop like most irs cars will do. I still didnt risk it on the irs either way. Only thing to grind if you have a irs is the top of a few bolts( brake line bolt, and a bolt on the side of the irs mount if you run wide tires) and also alittle off the bottom control arm depending what size rims/backspace you run. I ran the stock 3.55s and about 600ish hp and had no problems.

Damn 600HP is pretty stout. I will probably never get close to that. I'm thinking that a 15" wheel/slick is the best bet for me. Anyone have a 15" wheel for sale??? lol..

I'll probably keep the 4.30's, I don't plan on going to a 1/4 track very often. Anyone have an idea of which gear/RPM's I will be going through the traps at??

There is a calculator online somewhere that will give you an idea.

The more I think about it, you would probably be ok with a radial. It handles much better on the track too.

Street Radial, not ET Streets. Thats two different tires. I would run the 275/60/15 or the 295/55/15.

If its going to be absolutely track only, these "work" the best:

Ive got a set of 275 60 15's mt drag radials you can have for $40, $50 bucks and ill mount them. No cords showing but they are down to the wear bars just so you can give them a shot before buying a new set.

[bababuschka]

I might be able to do that, but first I gotta find a set of 15's. Would the MT's handle a drive from the house to the track and back. I was thinking about just swapping sets at the house before I go to the track and then put the DD's back on afterwards.
