28x10.5 SS Guys...What are you 60 footing?

Like the title says, what are you stock suspension guys 60'ing on a 28x10.5? We've been dealing with wheel spin issues all season and we are finally getting close. Looking for higher powered (775+), automatic car info. Thanks

Last season with our nitrous sbf with a glide and 3.89 gears we went 1.20-1.21 on good tracks and 1.25-1.26 on mediocre tracks.
28x10.5s tires at 3350lbs. Wolfe rear suspension, single ARB, QA1 shocks, 125lb springs

3320 UPR upper and lowers with qa1 double adjustable shocks factory mustang springs and MT 3055S 1.34 BBF on NOS 5.60 1/8 mile 127mph still working on it. 3.89 gears Powerglide. going to try more gear.

front spring length and weight rating is very important as well as front strut. I have never had too little traction but I have had wheelie problems in the past because we didn't make enough power for our setup.

On our current setup we are running the 29.5x10.5 tires and are in the low 1.20's again with our turbo setup but we are not even close to how it was setup as a nitrous car. our front end is limited to 1 inch travel now and a full tight setting on the strut. The rear setup is different too. We had to lower the front and raise the rear to get the IC where we wanted it with our new power. It used to be under our butts and now it's out at our feet. Too be honest after adjusting for IC and setting our ARB to 1/2 turn preload on the right and getting the weight right side to side I didn't even check the pinion angle. I probably won't either.

What's your current setup? springs, struts, arb, weight bias, etc...

Front:
Strange 10 ways
UPR Coil Over
14" 175 spring
Rear:
Strange 10 ways
Double adj lowers
Team Z DBl adj Uppers (relocated)
GT spring with 2 1/2 coils out out of each side
uPR ARB

3055S Tire, 4.10 gear
58% over the nose (iron head)
Car weighs 2960 race ready

IC is right at 38.5" and AS is 141%. IC height is 10.2 inches
Been working with Team Z for a few months and the best 60 ft to date is a 1.401. Still spins 1 revolution before the car even moves, which is down from 2 1/2 or so. Front has been on full loose and rear is 3 clicks from full loose. We're think the converter is still too tight

1.33 60ft. 29.5/10.5 Stock susp coupe... QA1 coil overs all the way around..

I didn't think Dave would let anyone run 14"springs. I don't know anything about his relocated stuff.

If you have Dave Z working with you then there is nothing we can say here that is better. He could get bicycle with a small block to hook I think.

Lol, you are correct with the bike! It seems that he like the 14" springs for BB cars. The 12" is for most SB cars.

Best so far with my junk is 1.33-60' with the 28" tires. We haven't been to the track since the Bash, too damn hot here! Sixty had dropped off a little, but I'm still playing around with IC. Once I get it nailed down, I'm confident it will 60' in the 1.20's.

sad to say my 60's on a 3055s is a 1.31 , just wish i had more time to test ....

Same thing here Nick! I've had some personal issues going on which have prevented me from doing anything and it's been to dang hot anyway. But now all is good with the personal issues, just don't have the funds to do much right now .

been a 1.29..............but it was a W so it dont count.

1.29 was my best when I ran 28 x 10.5's

I had a 1.37 60ft on a 275 M.T. Radial mounted on an 8'' wheel. The next pass it blew the tires off. That was with 90/10 Lakewood struts, stock front springs, Strange economy adjustable rear shocks and stock rear springs. I have never bettered that mark after going to QA1 adjustable front coilover conversion, Varishock rear coilover kit, adjustalbe lower control arms and an Anti Roll. I'm sure it's my chassis tuning skills, but something to be said for the K.I.S.S. system (keep it simple, stupid).
