Default stiffer but not lower

Hi all, after a bit of advice, I am looking at doing a few track days, but also need to use my car fairly often for running around in, its a my00 turbo 2000, on standard suspension.


I would like the suspension to be a little stiffer for track use, but all the sports springs etc for sale I can see, seem to be lowering springs, and I am more than happy with the ride height where it is, as I have no issue with speed bumps etc round town.


Would strut braces stop the roll in corners to an extent, or am I going to have to go for a coilover option?


Looking for a cost effective way to give a little more stiffness on the track.

Key question: how much has your existing suspension sagged in 15 years?
What's the distance between the wheel centre, vertically up to the arch?

The most cost effective way to stiffen your car up would be to uprate your anti roll bars, it won't be that much harder for road use, but a lot less roll in the corners.

If your suspension is 15 years old I can't imagen your dampers are as firm as they was when new. Maybe a set of fresh dampers and bumpstops would help without lowering your car.

The Impreza P1 lapped mira at157mph - 19mm front bar, 20mm rear bar - you should already have those bar sizes.
What are your wheel centre to arch measurements?

As 2pot above asked, what are the heights at the moment?

If you are happy with the height, you could consider just changing the dampers for uprated items such as the ones used in our Ezifit kit. This will tighten things up but still give good compliance on the road.

Rear's a bit low, for an un-lowered Impreza, unless you've got a full tank of fuel?

Your springs are fine then.
You could put on stiffer springs, but, not on your standard dampers. As they would not be able to control stiffer springs.

Re: Your 92-00 Impreza strut - what we need to know is, what are we buying?:
Are your dampers equivalent to a kyb excel-g/AGX on setting 2 front, setting 4 rear?
or
Equivalent to kyb agx on setting 3 front 5 rear?
or
What spring rates are they designed to match?
or
The dyno graphs, so we can work it out for ourselves.

Rear suspension has most effect on handling. I would suggest swapping your rear anti roll bar for a stiffer/thicker one and then taking the car for a drive to see how you like it.

We do 2 different dampers. Our black ones, which can be used as a replacement for stock, and our Red Sportsryder ones which are a performance item. However, even the black ones are valved different from stock. They are not "an equivalent" to anything specifically. The valving is designed and specified by our R&D guys in Australia. You wont be surprised to know that i wont be posting the dyno charts for these.

Normally, with our lowering coils, i would recommend our Red Sportsryder dampers, though i have used the black ones with them before with good results for a more comfortable ride.

OK
What rate are your 92-00 Impreza lowering springs?
