drag rear set ups

Hey all

Im looking at changing the rear end of my r33 gtst. runs about 400kws at the wheels. im struggling to get any traction even on a well prepped strip and slicks.

Below is a video, if you turn the sound up you can hear im on and off throttle the whole time and spinning/loosing traction the whole time.

At the moment it just has a welded diff and lower springs with soft shocks,

 

Starts i bog down then i struggle for traction when im up and running

 

What can i do to sort this??

Look for posts by hash pipe johhny on the topic.  He's posted a number of times what you need to put into the back and set up for better straight line traction.

wallah

you need:

• traction rods, extend them about 10mm - this will reduce the toe out ramp and camber ramp
• camber rods, run about -0.5 degree or even 0 - because drag car
• delete the entire HICAS rubbish, i.e. get a proper HICAS eliminator that deletes the ball joints for the hicas system
• get a proper mechanical diff, the VLSD is aids no matter how much is "locks" it's all smoke and mirrors
• subframe lock collars
• diff bushes

Then alignment:

• Toe in about 2mm each side, Nissans naturally toe out on squat
• not too much camber
• don't lower the car too much you don't want the control arms pointing upwards

I have about 370kW+ at the rears and I barely light up 2nd once the tyres are warm... albeit these are NT01, with the NT05 2nd gets a little silly.
