Bilstein Coilovers - 33 Gtr

[tk80]

Hey guys

got my hands on some second hand bilstein coilovers to suit a 33 gtr. they have helper springs on the front which are eibach....and the other an unknown spring (see pic).

first question....are these good for a track only gtr?

obviously i need to have the spring rates checked and the whole things looked over. where's the best place and around how much am i looking at?

thanks

the best place in sydney to get the springs measured and the shocks tested is bilstein/heasmans in tempe. they are excellent.

as for how much it costs, give them a call. and just from looking at them they are pretty heavy springs, up around 10kg/mm or more I'd say.

They look familar... Can I guess you bought them from a guy in qld? If so then I think you will find they are about 14kg/mm.

You can just get some lighter spring rates and have them revalved to suit providing the internals are still in good nick.

where do you think you've seen them?

why do you think they're 14kg?

Gary at superior suspension AKA sydney kid could help you out.

First job, read the numbers embossed into the Bilsteins, around the shock body, down near the lower mount. Should be something like B46------

Second job, read the following thread, measure the main springs and I will work out the spring rates for you.

thanks in advance gary

(didn't take spring off)

coil od: 85/85mm

That Bilstein part number is for a rear shock for an R33GTR

If that's the rear spring rate then it's too high for a track car on "R" type tyres, let alone a road car. It's an OK rate for a front spring on a track car, but a little high for a road car.

thanks gary

i'll try to measure the front springs shortly.

how will the helper springs effect the situation?

what would your target spring rate be front and rear for a track only gtr?

is the shock a good platform to start from? or should i be looking at a whole new setup?

[tk80]

i finally got around to measuring the fronts...

coil od: 90/90mm

wire od: 12.75mm

# of coils: 7.875 (very close to 8)

bilstein part number: 734 1471 H001

Gary, could you please work out the spring rate at let me know if the shock is good or bad?

Also, if you could answer my questions in my post above it would be great.

thanks again

helper spring does nothing except keep the spring captive when the shock is at full extension. it is fully compressed by the cars weight any other time.

you out there sydneykid?

Thats nuts; 4 kg at the front and 6.5 kg at the rear! If its were 6.5 at the front and 4 at the rear it wouldn't be bad at all...
