New Suspension and Rear Diff Bushing

[Texaschwag]

Posting this up for some in site, I feel like this car could be in the 7's or should have already been. I installed UMI non adjustable LCA and a double adjustable upper control arm and received a bunch of popping, thought it was the drive shaft.

I installed the Rear diff bushing from BMR and rear is now solid.

Only track open so I am limited to the 1/8th and only got one pass in. Place was packed.


Mods and Notes:

SCT 93 tune
Suspension
Slicks 28.5x9x15 15psi cold
WOT Box
Stock 3.73's
Full Stock exhaust
Stock air box



Thanks again.

adjustable upper control arm

to include UCA mount? if you used an aftermarket UCA with the OEM mount, that could be the resulting popping/clunk you hear. Was the final torque on the new UCA/LCA done with the suspension loaded?

suspension

- what springs?
- what struts/shocks?
- what is the pinion angle set to?
- auto or manual? (guessing manual if you're running slicks and wot box)
- launch RPM?
- spin or bog at launch?

Thanks again for all of the help. I feel like my 330 was a bit slow as well.

Stock UCA Mount and torqued them all down with load. Also no more popping after installing the bushing.

- what springs? "M-5300-KF"
- what struts/shocks? "Stockers that came with Brembo Pack"
- what is the pinion angle set to? "Setting it this week to -2, should I set with the slicks on and i have the stock 2pc. Do i do this from the rear section and diff yolk?"
- auto or manual? (guessing manual if you're running slicks and wot box) MT82
- launch RPM? 5k Side Stepped the clutch not on the 2 step
- spin or bog at launch? No spin just go or atleast felt that way.

After reading my original post, it is a bit confusing. I'm hoping for as much help as possible to get this thing in the mid 7's.

I feel like my car is under powered for some reason.

"Setting it this week to -2, should I set with the slicks on and i have the stock 2pc. Do i do this from the rear section and diff yolk?"

the adjustable UCA will be used to adjust the pinion angle. set it with the tires you'll run at the track and with someone (or your equivalent weight) in the drivers seat.

here's two videos that explain the process:

Awesome. Never would have thought of the weight of me in the car.

Thanks again and hopefully the weather holds out this weekend.

You're in the general ballpark, depending on the DA.

My car with similar mods ran this- (I had an offroad x-pipe, but the stock 3.31 gears and 18" street tires)



Usually, a tenth quicker at the 60 would equal a tenth quicker at the 1/8th. So in theory, my pass would've been a 7.77 @ 91 if I was on your slicks.
