Default M6 ET streets suck

I have an M6 cam only car with a 430 gear, I have 275 50R 15 ET streets and they suck. 2.06 is the best I can do and got warned again for ripping the rubber of the track. I did better on 17inch nitto's

What 27 inch tire will dead hook? I only do about 3k miles of street driving per year its about 80% track car. I have a bigger cam and 100 shot to go on the car still.

The ET is an incredible tire.

What are you doing for a burnout? what type of clutch are you using? how are you launching the car? is it hopping or blowing the tires? Whats the rear suspension?

The fastest radial cars in the country run that tire (with a little more sidewall).

However, being MT and if you don't class race and are not restricted to a specific size or type, an actual slick may be up your alley.

...but as far as a radial goes....it's not going to get any better then what you are already working with. Look elsewhere first...

I roll the cluth out hard and I've tried dropping it from any where from 4-6k bog or blow the tires up. Mcload twing disc, built t56, 9 inch. No front sway bar, strange coil overs up front set pretty loose, Hals in the back set pretty loose, umi body mount torque arm, UMI control arms. I get some pretty heavy weight transfer with alittle body roll if I hammer it at 10 miles an hour or so. Its the hit of the tire. 2nd gear burn out and I get them hot. I've also tried just doing a quick clean off, hardly any smoke. PSI as low as 15. Still not working. I know I need a 27inch tire min, maybe a 28. New cam and spray I should trap around 127 or so.

the tires work best if you dont shock them , my brother has a auto car and will blow them loose when he flashes the stall but hooks like glue if he stands on the converter . so i think you still have to slip the clutch.

My old TA would cut 1.60s all day long on the same tire but on a 16 inch rim, drop the clutch when the shift light cam on. Maybe the tires are just shot, they were on my old auto TA I bought but have no idea of their age.

Try the hoosier radial, i've heard the sidewalls are a little softer so they are more forgiving on the M6 cars.

I ran 17" ET Streets and they hooked like a bitch! Pulled the front tires with my relatively mild setup with stock shocks/springs and at full weight!

This is all just my opinion....

I feel that for the amount of gear you are running, paired with the 27" tire is making it difficult to get out of the gate. Like mentioned before, that tire doesn't want to be shocked by the clutch. In order to get that thing out of the gate you are really going to have to slip the clutch and burn it up a little.

Stepping to a 28" tall tire will help knock down a little bit of that gear, and it will give you a little more sidewall to take the hit....but key is going to be how you come out.

I have a 26 inch tire now, I had 4.11 but just bumped them to 4.30. Sold a 9 and got talked into swapping third members. I need a true 28 inch tire, N20 is going on the car really soon.

What tire should I get a 27 will get me 125 @ 6700? If I get a 28 it will be less RPM but I dont want to hack the car up, I'll cut the bump stop off but rolling the fenders etc not cool with that. I have MT sportmans up front, skinnies can I mix these http://www.summitracing.com/parts/HOO-17500/
Those are the tires, i'm thinking about getting opinions?

15 inch et streets are bias plys or radials?

with a stick you want bias plys to absorb the clutch shock. if you are bogging, have you thought about adding power?

i have run both, found best results with et streets at 15 psi for a slight amount of spin (maybe two turns to save drivetrain on street car) and around 22 psi with et street radials.

3500-4000 dump is a bog any high and I blow them up and just feather the throttle. It has the street radial version. Those 27 inch tires I have picked above are they good enough???

http://www.summitracing.com/parts/HOO-17601/ will this tire rub or require the fender lips to be roller? another option is this 27.6 for diameter

That hoosier 28x11.5 is going to be very close, if there's a 10.5 inch wide version of it, get those, they will be a little easier to fit in the car (less beatign on the front lower inner fender)

like stated before radials suck on a m6 bias ply is the way to go. and i would just roll the fenders and get the tire you want under there you will never know they have been rolled if done right

I didnt realize he was running ET Street radials. I guess i should have paid more attention to the tire size he listed. Makes more since now.
