Cressida Drag Strip Suspension Set-up

**slydin-cressy-style** · 13-02-2008, 03:54 PM

Hi guys

Im just wondering what all you Mx83 Drig Stripp-ers use for your suspension set-up?

Im particularly intrested in shock decision but spring info would also help

Tell me what your chose and if your happy with your set-up or not

There might have been some info on this issue before and I DID LOOKso pleese dont hurt me

lol

Thanks guys

dont know what they use,
but coilover swaps from jzx81's are common, spring rates and the rest i have no idea

i would personally put some adjustable konis in there and leave std springs to start with, once you have dialled the shocks in accordingly you may find that you need to go stiffer in the rear but this would all depend on how much it squats, what alignment you run and tyre design/compound you run.

as with most things car related what suit you vs what suits others can vary by a fair degree.

cheers

Any body else?

Forgot to say that im indefinately running king springs also to make it look like sex on wheels

I do know that they are a thicker spring

More intrested in shock choice

Depends if you want to keep it street drivable.
The way to go is hard in the rear and soft in the front.
If you can get your hands on some Pedders 70/30 or 90/10 shocks, those are ideal for the front, as they let the front of the car lift easily, but resist it dropping back down again. It also has the effect of pushing the rear wheels into the road even harder due to the weight transfer.

I just have Pedders comfort gas shocks on the front of mine, and KYB rear shocks (unknown model) and it seems to hook up reasonably well (1.86 60 foots on Falkens). I might need to go harder in the rear shocks, and get some urethane control arm bushes.

What is the reason for going for a hard rear end, is this an attempt to reduce axle tramp or the amount of camber generated by the tyres - like a commodore does when the back end is lowered alot?

As i have never had a car with 90/10's, are they stil driveable?

Are the 70/30's milder?

70/30 is milder, but still would make the car an understeer pig in corners, with possibly dangerous handling. You would have to draw the line between drag and street at this point. That is why I went for the comfort gas (plus they are cheap haha). Also the 70/30 and 90/10 shocks are hard to come by now I think. Don't forget to get soft springs for the front too.

You'd have to chat to Shane (1JZ747) for more info on his setup, if he is willing to divulge.

I'd say the reason for hard rear shocks & springs is to reduce squat. May also help with axle tramp but not sure.

The urethane control arm bushes in the rear help with the camber when doing launches, maximizes the tyre contact with the road.

Isnt squat a good thing?

Ive heard of cars having 0 degrees camber in the rear to have as much grip surface as possible

**amichie** · 14-02-2008, 03:21 PM

Hard rear is far camber control to maximise tyre contact patch.

**jak** · 14-02-2008, 07:56 PM

we use tein coilovers in the rear. dont know any of the specs but.

smaller spring lets you get a bigger tyre under there.

i dont think its really nessecary unless its going to be an all out drag car.

not sure if this is the same for IRS cars but solid rear end cars actually try to lift the rear end on launch. Think of it like this. If the body of the car is trying to move up, then that is effectively pushing the tyres down into the ground to improve traction. unsure how that works with IRS as that shit just freaks me out

**The Real Roadrunner** · 15-02-2008, 05:05 PM

its extremely hard to get a decent amount of anti-squat into an IRS car, thats why it is more vital to get the rear end spring/damper combo and alignment correct to suit the tires you run.
