Better 60' times

Better 60' times

--------------------------------------------------------------------------------

I didn't know where to put this one so here it goes,

A friend of mine just sold me a pair of McCreary L60 Road star DOT slicks. They measure like 26 in diameter and 10 in tread width. They are about 10 1/2 to 11in in total width. I am about to buy a set of rims to mount them on but was wondering if any of yous have experience with this tire??? My last time at the track my best 60' was 2.33 and I am really trying to get it down.


Thanks for your time!!

how about you tell us what car you are working on?

leaf springs or coils on the rear make for different things to change or alter to help traction.

Gear ratio , tranny , converter stall? , manual tranny?

how about you tell us what car you are working on? - 85 Olds Cutlass. 307 pulled and 350 with AFR195, ex284 and the rest of the goods no power adders.(front sits a couple inches high since I have removed alot of weight) I would say I am in or over the 400hp mark.

leaf springs or coils on the rear make for different things to change or alter to help traction. - Rear suspension is redone with moog replacement springs,boxed lower control arms,tubular upper control arms, new axle housing bushings, 3 way adjustable shocks. Everything polyurethane even the coil spring isolators, stock rear sway bar. Front sway bar removed. Battery in trunk passenger side. Just check out the Photo album.

Gear ratio , tranny , converter stall? , manual tranny? 3.73, 2004r, 3,000 stall.

I was wondering if anyone had experience with the above tire I mentioned??

I know that if I really wanted to put the power down I need race springs all around and a pair of slicks. just haven't got there yet.

My last time at the track my best 60' was 2.33 all over the place and ended with a 13.33 @110 I am really trying to get it down. That was then now I have a full msd ignition and 50% underdrive pulley kit. The motor really likes to go.

i was running 245/60/15 street tires with a quick 1into2 smokey burn-out. The car is very aggresive off the line. footbrake and all.

I didn't relize you said drag radial.........

With a 110 MPh trap speed your engine is making some pretty decent power.
I ran a set of these in the past and they do require a pretty decent burnout.
1.80 60ft is what I think I pulled with them. That was quite a few years ago.

good luck....

The thing is is that I have been telling people about my trap speeds and they cant understand why I could have a 13.33(total stock ignition). And now with the mods Speed shops and racers that I talk tell I should be getting low 12's with my car if I can get a good hook.

An air bag inside the right rear coil spring, and play around with the air pressures, start low go up 5 psi at a time until it changes back for the worse.

This is a common practice.

Another big thing would be to lower the frontend if it's too high, at least down to level with the rear if not lower.

EVERYTHING COUNTS, have the alignment checked and set the toe-out to minimum recommended, and make sure it tracks straight with the rear axle.

What front shocks and what valving rates?

What front shocks and what valving rates?--regular stock replacements. I quess I should put an order in for some moroso trick front(and rear) springs and adjustable 90/10 type shocks, that is where I quess you were headed with that one.. The front end is probably killing me because of the springs and shocks, being that I ripped the olds 307 and the ac and replaced with a 350 with aluminum heads and fiberglass hood. The 307 so freaking heavy compared to the 350. The front end is just a little higher than the rear which is crazy because I have brand new rear springs in. I quess I am getting to he piont were I have the power, now I need the wieght tranfer.

90/10's or even 70/30's will definitely help you out, have you checked to see if there are more body parts made out of fiberglass, I know I could get both bumpers, hood, front fenders, and trunk lid, for my Malibu if I wanted to go that route.

The reason I mentioned the air bag is if you have much chassis twist when taking off the line, about the only you can determine this is to have someone take a video of your car and look at it closely for front rise, rear drop, and twist, which will cause the right rear to drop more than the left even with the sway bar (which actually helps with this too).

I was already getting the camera ready. I was discussing that with a friend. I want a back and front shot. All this talking and all I wanted to know Is if anyone had experience with the particular tire. I like the conversasion though. When I get the video I will try to upload for yous. It will be sometime in mid-late april I will be headded to atco. I just got the wheels in 15x8 - 3 1/2 bs Draglites in today. Had to send the msd sparkplug wires back because they sent me the wrorg ones. Getting the cooling system ready and I will be on my way. Just have to figure out what is going to brake first when I finally get that first hard hook-do you want to start taking bets?

So it is anomonous dissision that I have to heat the McCreary l60 (dirt) tires pretty good??

And the air bag thing- I think I rather just go with the race springs.

Have you thought about something that adds anti-squat, such as Southside Lift Bars or something along that line?

well they do require a good burnout and I am sold. I got a 1.745 and ended with a 12.25@110. That is with stock trans and rear, can't wait till I get the rest of the work done and the front suspension done. Thanks for the tip on the burnout. since I have the one Leger I foot-brake it at 2 grand.
