was wondering if anyone is using a full slick their cobra with the irs?.. im used to using drag radials.. was wondering if a full slick will help better with my irs with level 5 halfshafts... any input thanks
Any stability issues at the top end like So Many other complain about with the ET Street's tistan?
With radial street tires up front, I let out on my first pass and it swayed so bad on my second pass that I almost hit the wall. I put it on the trailer and went home and ordered a set of bias ply front runners. No stability issues now. I wouldn't try to mix them again.
I run slicks on my Cobra at the track and drag radials on the street. Stick shift cars generally like a full slick or street slick (any bias ply design) better than a radial tire. It is also easier on drive line components because the softer sidewall of the bias ply design takes to the initial hit/shock of a stick shift launch, easier than hitting on the hard sidewall of a drag radial.

It is not from the side wall.
That is what I'm talking about.
And still not credible, One guy said it, another repeated it and another and another.
Fact is the ONLY reason DRs break shit and shock more is because of hop. And not even hop that can always be felt as up and down hop. Basically what the pros call tire shake.
The tire goes into a grip/slip/grip/slip thing.
Soft side walls on slicks soften the hit on the tires and that is it.
Once that tire wads up it is full on to the driveline.
The sidewall on the DR shocks the tire and sends it into hop which in turn shocks the hell out of the driveline.
So indirectly I guess they are somewhat right.
There is no way a 1.7 60' on DRs without hop is harder on a driveline than a 1.5 on slicks with the wheels in the air.
As said, DRs hop and that is what breaks shit.
It is a big misconception that the "Soft" sidewall is what saves parts, there is more to it. The fact that slicks grip and most don't have the HP to send them into tire shake is the bigger part.
Sorry I just get sick of hearing the slicks are easier on the driveline than DRs.
While slick may not break as many parts (On street type cars) as DRs do the explination everyone gives is too simple and semi wrong at the same time. It gives the impression that just getting slicks will solve all parts breakage and is easy on the driveline.
Keep racing and you will break something. No if, just when?
I want someone to find some credible info on this. Not another message board where people repeat the same thing that you all have been hearing.
The tire reps I talked to will not agree.
Why can't you mix slicks and radial tires?
