Pretty much anytime you put in a part that is going to make your car handle better, its going to drag race worse.

I was going to call Tein and see if I could get some custom rear springs for drag racing since its so easy to just change the springs out in the back of this car. and then I was going to use my JIC camber rods and just count the turns and go to as close as I can to straight or even a little positive camber (for when i plan to drag), and then count the turns and go back to my regular settings (for standard use). At least this was what I was gonna try out for this year... not sure how much room I have to work in those JIC arms.

The thing is...with a compromising setup you will always be giving something up. As you are right now. So I really don't see how you could make your straight line traction any better than it is right now without losing handling.

As for the traction bars....here's a link..you can probably find them cheaper.

I do agree the type Flex is way to stiff in the back for a drag set up... My shops car ran 8.33 @ 177mph on the Type Flex / GT spec rear lateral reinforcment / BF-G DR's The car just Hooked!

Though you just further proved my point. A 177mph trap is a 7 second trap with a GOOD launch. Obviously that car could get out of the hole harder with better weight transfer that can be had with a more drag condusive setup which is probably not allowed in the class that the car competes in.

Contact Swift springs. They have a WIDE range of spring rates that will fit on just about anyones coilover setup. A member here swapped out his 7KG front HKS springs with some Swift 8 KGs. They fit right onto the strut body and perches.

Thanks they only make OEM replacement type 16mm drop... I need something that will sit on that collar... I'll call Tein see what they have...

I just ordered my emanage ultamite through forged internals (thanks Sharif). I have the APS TT set up with the bigger actuaters, and 650cc injectors. I made 620whp at 13psi but thats as far as i could get with the aps injectors and the unichip. So now i have the stuff i need to go to 16psi which should get me close to 700whp or more on 109 octane And yes i have a fully built engine, with 10.6:1 compression thats why i dont need much boost. Does anyone know who has the most HP on a street driven 350z?
