LOL i was about to ask that coz i couldn't find them either.

i booked myself in to have the boys have a look over the car on Wednesday. $15 for a check - which i'm pretty happy with.

sydneykid did a big writeup in another thread about good suspension settings. maybe that will help?

[Frink]

any advice that SK gives is always good....

[sigsputnik]

i clipped this bit of info from his post a while ago, if it helps:

Front Camber -1.00

Front Caster 7.00

SAI 9.00

Front Toe 0.00

Rear Camber -0.5

Rear Toe 2.00 mm in on each side

but i'm pretty certain there was much more in the original thread.

they are very roadish specs. Around a track, you'd probably want another 0.5 - 1.5 degrees of neg camber on the front, and maybe another .5 on the rears. Caster is fairly good.

Then again, all this depends on the track.

guys i recently bought a R33 with coilovers.....I have no idea how to adjust them....can anyone help???

You don't really............well you can if you know what your doing.

For ride height:

You have to remove your wheel, have two 'C' spanners handy and then adjust away turning the big rings at the bottom of your spring. After this you'll need a wheel alignment. So I would go to one of the afore mentioned suspension shops and let them do it all.

For ride dampening:

If you have damping adjustment [a click turn adjuster in the centre at the top of your shockie] then you can dial in anything from hard to softer. Upmarket models have this, the not so upmaket ones have no adjustment, the damping is fixed. Then there are extreme upmarket ones that don't believe you need any of it because their product is used by God.

It's next to powertone exhaust centre. Not sure what the street is but just up from the comm bank and that little roundabout

yes on the bottom of the shock there will be a dial, some have it on the back parcel shelf, but mostly on the bottom, there will be a left and right action for dampaner control (bounce back) left is for softer right is for harder more aggreisve.

Shit i didn't know you needed a wheel alignment when the suspension is altered. I was playing with mine the other day and the rears are as low as they go...fully sick...obviously im not going to leave it like that but for any adjustment do you need to realigne your wheels?

[tridentt150v]

As you wind down your suspension you will 'squat' the car. This means that the inside of your tyres will be the main load bearing contact point. ie your camber is changed. The insides of your tyres will scrub out.

The amount of camber you end up with depends on the amount of adjustment you dialed in. Your tyres are not moving in a straight line, they are on an arc [imagine you remove your suspension and then pick the car up and the wheels dangle, they swing down and the tops hang out and the bottoms swing in]. The back tyres are less affected because they are on a full axle.

So any adjustments you make are movements about an arc.

Or thats my understanding of it anyway.

Somebody else may be able to add more!
