Tein SS installed

[Richee]

Woo hoo is about all I need to say.

What a difference these things make, the car is now much flater thru the twisty stuff and corners at speed without feeling like its going to do something silly. Currently they are set 10 clicks off the hardest setting.

Its great when the suspension is doing the work and not my backside, I took off down the road and hit a bump and nearly went airborne, will give them some time to settle before I play with the settings.

Only thing is now I have some movement in the steering rack under hard cornering

I agonised over different shocks/springs but now dont regret spending the extra.

All in all, one happy chappy.

You seem really pleased Richee. Did they lower the car's ride height too?

[rvlovell]

the teins are about standard ride height straight out of the box. I dropped mine about 10mm. I was surprised at the lack of adjustment availible for lowering. Strangley there is more adjustment for raising.
I guess thats for people who want to go offroad in a convertible

Pleased, that I am.

As rv said, I dont think its much lower, but it looks lower esp at the rear, maybe its just sitting better if thats possible !

,Hows your new tyres JBT ? edit : silly question. I see the other thread.

Jury is out at the moment.

My C drives were a bit ho hum for a few hundred k.

[butters]

the bloke i priced from fulcrum said they are suposed to drop ride hight 25mm aprox. we went out and measured my car and they would only drop it about 5-10mm.

i would imagin that everyone has saggie springs and therefore it doesn't drop the car that much because they refer to stock ride hight on fresh springs. same thing happens if you lift a 4wd. i put a 50mm lift in and it went closer to 75mm on what it used to be because the old springs were saggie

Isn't the point of the adjustable spring on the Tien (and similar) to adjust pre-load, not height? Or do the Tien's offer both?

When I spoke with the gents who sell the G4 coilovers (JustJap) they said that they saw the most 'warranty' returns from guys who tried to use the spring adjustment to lower their car. They compressed the spring to reduce it's height (overtightened the spring pre-load) and blew the top off the strut.

AFAIK, the Tein SS is set for a specific ride height which is a bit lower than standard. If set lower, the suspension travel is reduced. The Tein Flex is ride height adjustable but is not approved by all (any?) Australian states for road use.

adamjp, what do you mean by preloading the spring? I'm fairly sure the teins the purch is only adjusted - hence change in height. Or have I got it all wrong?

[adamjp]

Phat,

On coil over suspension you can adjust the coil seats. With most of these setups, the intention of the adjustment is to pre-load the spring. You pre-load the spring in order to ensure the weight distribution is what you need for the track you are on and the conditions you are in.

A simple MX5 will carry more weight on the drivers side tyres when only the driver is on board. You adjust the pre-load to place more weight on the lighter tyres, balancing the car. This is what is known as 'corner weighting' a car.

Grassroots has a reasonable article on it here

I grew up with racing motorbikes, on a bike one of the things you adjust is the pre-load to get the correct suspension tuning. I use the terms I know.

4Strokes has a discussion of it for dirt bikes here
