I am looking for some help trying to get my older GRT to work.
Its an '02 with some updates and put the newer (1/2") 4 link brackets on this year.
We are on a smaller track ( they call it a 1/3 mile, maybe around the outside!) with tighter corners that typically gets pretty slick come feature time. We run D55 tires (WRS2) with a WISSOTA engine (358 steel block with Brodix SPCH heads). We must weigh 2300 lbs after. I have run this car for a few years and have had good luck in the past at this track, but haven't run there in a couple years and took all of last year off. I can keep up on the straights, but lose some through the corners. The car is somewhat tight on entry and need to use the brakes to loosen up entry, then get a small mid-corner push of the gas that makes me wait a bit to get back in it hard (typical GRT). I don't attack the corners hard, but prefer to be on it hard before the apex. When it really gets black I struggle with forward drive on exit, but if there is moisture in the track we are pretty good.
The front end is standard GRT with '96 and up Black spindles, left lower 16 5/8, upper 10 1/2, right upper 7 3/4 mounted outside, lower 17 5/8.
The 4 link bars are in the standard location and 19 1/4" J-bar mounted in standard location.
The 5th coil has a 325 spring all the way back with good travel, 400 on the 6th.
We scale as GRT recommends with 20 gallons of fuel (alcohol) and about 50 lbs of lead in the seat to make up the difference between my weight and their fictional 200 lb driver.
Stagger is 1" at the front and 6" at the rear.
The corner weights from scaling are:
LF 523 RF 464
LR 654 RR 579
The shocks are Integra double adjustable and the springs are:
LF 500 RF 375
LR 250 RR 225
I have gone basically back to basics after trying a bunch of stuff we didn't have to do a couple years back. The competition has gotten much faster and I'm trying to catch up!
Sorry for the garbled info but I'm beating my head against the wall trying to figure this out.
Any feedback would be greatly appreciated.
Thanks in advance,
Tim
