any input would be great also the car will be making around 400-450 so lmk if there over killor not.

 

Gearing plays a vital role in choosing proper slicks as well.

 

running a ls trans with b16 1-4th ls final drive

 

Im running 13x10 5" backspacing.

 

how wide are your slicks though? how close is the slick to the upper ball joint? if im running 9 or 9.5 slicks should i be using 10" wide rims or 8" wide rims?

 

I wanna say that i have a bout an inch of space between the tire and the upper ball joint. I can get you a exact measurement if you want.

 

ok but do i need a 10" rim for a 24.5 8.5? or is it better to run a 8" rim i was told wider will give more contact patch when air down ? where 8" will make it bubble up in the middle ?

 

also hows your fitment between tire and spindle?

 

As i posted in your other post i can get you a measurement if you want. I think i have about an inch of gap between.

 

how wide are your slicks ? any incite on how wide of a rim to go with a 8.5 mh slick

 

I ran an m&h 24.5x8.5x13 on a 7.5 lenso wheel for a year. I cut a best of 1.71 and usually 1.80-1.88 60 foots.

I switched to a 13x10 wheel with a 24x9x13 MT and my first pass 1.64 with a best of 1.58

From my experience both the M&h and Mt worked well. Either tire will do fine.
Also from my experience the wider wheel really helped put more tire on the ground.
The 13x10 is a little much for most. I had no issues but my car sat high. still oem front end.

I would say with 500ish whp. run either slick but get a 9" wide wheel. It is plenty enough to make all of those tires have a good contact patch.

 

This is my car with a 13x10 wheel and 24.5x9x13 MT slick. sticks out of the stock fenders a few inches. I had to roll my fenders to clear the tire.

 

What s your 60feet with these wheels and tires?

 

Ive cut a few 1.50's but mostly 1.54-1.58 range.

 

Very good,
why don t try 25"?

 

Never really wanted to . I might on next set of tires .

 

i ordered some areo 13x10 the hit my calibers cause the drop center area was in the wrong spot so i mite have to order new rims or run spacer. i have yet to run a pass with bars but ive been doing 1.9 60fts on my 24.5 8.5x13 m&h tires only leaving on 9 psi and 6800rpm

 

How much pressure in your tires before you do a burnout? Your launch RPM is really dependant on the track conditions.

 

like 12-14 never spins so never drop tire pressure
