I use the Spohn swaybar. Huge difference over stock. 1.32 is my best.

Here's some obvious questions that need to be answered 1st.

M6, A4, A3 -- otherwise what is the tranny set-up?
Rear-end? Stock, 12-b, 9" - gears?
Tires?
You have dropped the front sway-bar right?

These would need to be answered before your question is fully answered.

The rest of you suspension is not bad. BUT dump the stock rear-sway bar. Wolfe's is one of the best out there.

Build a signature box. Tell us about your car. Nothing can be that much of a secret. 600hp on an LT1? Are you spraying?

With that kind of power and rear-end set up, you should be easily in the 1.3's. As a nitrous "huffer" my N/A was 410rwhp, spray 150 shot out of the hole - mid 1.3's very consistently (new set-up is a different story ).

What are you shock settings? I usually run 3 in front and 6 in back.

Are you dead hooking, spinning? Try different tire pressure.

Of course one of the larger factors would be the track prep.

But you need to look at getting a better rear sway bar.

The last thought I have: have you had the car corner scaled? What is your pinion angle?

IMO: get a Wolfe sway bar; take it to a shop to get it corner scaled and pinion angle check (most will run -3 to -2). If you are near ThunderRacing, MadMan is the "man" to see.

Once you are looking for 1.2 and 1.3 60' all the small factors come into play.

(Oh as a side note: you are going to run out of gear, shoot 300 shot, almost 600hp = 800+ hp ... not going to make it to the traps - been there, did that on only 150 shot on 4.30's)

The car spinning pretty bad on the nitrous i have the pionion angle set at -2 degrees we have never corner scaled it but thats not a problem my boss has a big dog car his son runs and they have some so i can get them and see what it looks like
Shocks are set on 1 in the front and 5 on left rear 6 on the right rear

Also on the 4.30's we just run 1/8th mile around here there's not 1/4 mile tracks around.

So you are saying putting that sway bar on my car should get it down in the 1.30's IF everthing else i have is right?

Sounds good on pinion. Check out the weight front vice rear - mine is set at 52% front/48% back (I have a heavy iron block)

Before you spend $360 on a good sway bar (http://www.wolferacecraft.com/Search...ategoryID=18); try the weight first; try setting your shocks differently; I assume you have tried tire pressure.

"should get it down in the 1.30's" nothing is for sure, but it will not hurt - the sway bar will also help the car leave straight and level.

Remember track prep maybe the biggest culprit.

Nitrous, 4:30 gears and a 28" tire. You can get the swaybar but I think it's gonna be tough to hook that combo on a stock style suspension. I think it'll be asking alot of a 28" tire. Not that it CAN'T be done, but I'll be impressed if you get that to hook.
