Traction!?

[5ky-lin3]

Hey guys! Just a quick question.

After my last stage of installments my r33 gtst is now running over 220rwkw, however im having all sorts of trouble putting that power to the ground and before I go for any more power i think it needs to be addressed.

What suspension/handling upgrades are there out there that I should be looking at for my rb25?

I know a good set of tires is an obvious reason and also a reduction in tire pressure also helps but what other ways are there so I can keep it in a straight line? At the moment under full throttle and it cannot hold grip until the beginning of third

Cheers!!

Posted in the wrong section however what is the current setup on the car? (specs on shocks/springs, tyres, rims, camber, etc.)

[TiTAN]

get a suspension shop to setup your camber, toe, caster and such.

it doesn't matter how wide your wheels are or how good/wide your rubber is if you are carrying 5deg of camber on the rear, there are going to be traction problems.

As the other two said.

Get the alignment checked, if that is correct, it comes down to tyres.

I had near perfect traction with 280rwkw. Could plant the foot in any gear without issues.

All suspension (shocks/springs/camber) is all stock.. Unsure on what dimensions the 17" rims are but am just running average tires..

Well get some half decent tyres exp. like kuhmo ku36 for a start and then see how it goes and get a wheel alignment to make sure settings are fine.

[5ky-lin3]

After some quick research I have compiled a list of things that would help address this issue and improve overall suspension. What do you guys think? Have I missed anything?

Decent tires (Kuhmo Ku36 for street use)

Front and Rear Coilovers (monovalve)

Castor rods

Front & Rear Camber arms

Adj Tie rod ends

Pineapples

Nolathane Control upper arm inner bushes

Nolathane radius rod adj bushes

Half that list won't actually do anything for straight line traction.

On stock suspension you really should not be having traction issues if you have good tyres and a good alignment. Do those first before doing the rest.

[boostn0199]

As said above what you listed will help grip or drift where corners are involvrd straightline traction almost goes oposite with softer suspension zettings working better. The adj arms are only used to correct or customise alighnment settings wben you change the geometry for example lowering it.

So just get the tyres and you should find that solves your problem espcially at 220 kw

righto thanks for the help lads.. Think it has been lowered before i got it but has been a spring cut job

[Roffy92]

ahhh!

i am also having the same problem, just found this post while browsing so i havnt done any research yet,

but im also quite confused as my rb25 is still stock just running actuator pressure (nothing over 9psi)

i can take off smoothly (ie. im not dunping the clutch) and as soon as i get the pedel to the floor the ass jumps around like a mofo, if i grab 2nd quickly it keeps spinning the tires till i grab 3rd

as far as i know all my suspension is stock, but the guy i bought it off did say that it was really low when he got it.

ill check the springs tomoro n hope it wasnt a chop job too :S

thanks for the advice ^^^^^ i now have a list to run through

Cut springs well that would be a major culprit. With out set spring rates compensating for front /.rear transitional load... No wonder you got no grip

[PM-R33]

Haha now it makes sense. There is your problem right there - cut springs.
