Default Little confused after new suspension

The car is the 94z A4 in my signature. I was having a ton of traction issues before with it, i could never hook up and the rear end was always going right after the launch. I finally replaced the eibach lowering springs and high milage worn out crap shocks with QA-1 R series up front, set all the way soft and a set of the summit brand adjustable drag shocks (basically the same as the CE ones) those are set at 50/50, i also installed a set of Eibach Drag Launch Springs with the air bag in the right rear spring set of about 20 psi. The car felt GREAT i made 7 passes and on all of them the front end came up nice and quick, felt like the weight really transfered nicely, it didn't spin much off the line but my 60's and ET were slower than they were before the new suspension. Before i was cutting about a 1.8-1.9 60' and about a 13.4 1/4 on motor and that was with a conciderable ammount of spining off the line. Well friday night with the new suspension i was cutting about a 1.9-2.0 60' and a 13.6-13.8 1/4 but the launch really felt great, perfectly straight not much spinning off the line, any suggestions?

unfortunaly no video, one of the guys watching said it did sound like it bogged a little, why would that be, is it cause now that it's hookin it robing a little power when it hooks? and what should i do about that play with low end timing a bit?

You need alot more power to actually take advantage of a dead hook. You have to play with your launches, or hit the spray off the line and see how she acts. The closer you can launch to 5250 the better.

ah, well i was staged about 1500 rpms then stabing the throttle at green, now that i'm actually hooking i guess i'll try bringing that rpm up higher on the launch and see what happens. Thanks J

I don't see it in your sig, but if you don't have it you need a converter.

It's going to be hard to NOT bog off the line with a dead hook + stock converter; it'll pull your RPMS all the way down to 1800.

Probably why you were getting better times with some wheel spin off the line because the 0.2 seconds or whatever of wheelspin allowed your engine to get into a meatier part of your power band...if that makes sense.

hmmm, that does make sense, the guy i bought the car from said that it did have a converter in it but i havent been able to verify the size or even if it does have one
