Quite right. It's to do with a number of factors and roll stiffness/spring stiffness/roll centre is one of them. It's quite complicated and it's been quite a long time since I actually had to use any understanding of it, so I don't want to comment too much. Acutally I was hoping that roll stiffness wouldn't come up!

Anyway, Trinydex is also right. At the end of the day, if your tyres cannot provide the grip, you will always slide first...

Very, very true. Very well put.

So Wangracing, which do you prefer? Your evo or your Sti?

 

A wider track reduces lateral weight transfer and running really wide tyres are not always good for handling, I guess.

 

Has anyone put the stock regular EVO damper on a shock dyno? I think this is the only way to find out what spring rates the stock damper can handle. If the damper is overdamped for the stock springs, then it should logically follow that we can use stiffer springs close is length to the stock springs.

I am particulary interested in the Ralliart springs. These springs do not lower the car by more than 1/2 an inch and some have tried them and said that they have the same height as stock. They are 280 f and 307 r. They are 100 and 82 stiffer than stock front and rear.

Can the dampers last long with these stiffer springs? Will these springs cause the damper to become underdamped?

These are the questions that I have and I have yet to find an answer.

 

Well I thought my STI was the ultimate drivers car, and to some extent it was. No ABS or any other electronic aids, so if you were into the purist thing, it was awesome. Very rewarding when you got it right....very punishing when you got it wrong. I am into the competitive tarmac rallying thing here in aust. so in IMHO you cant beat the EVO here. Unfortunately we dont get the full spec C STI. If we did it would be a harder choice. But the electronic aids, which I was so against, are awesome in the EVO. Ran a mates EVO VIII in a recent tarmac rally and blitzed the STI's. Was such an easy car to drive fast and sooooo much fun!!!

 

^Same here... although my Sti isn't a purist like an RA or a Spec-C, it's more fun. But the evo's faster... anyway, just got me a hi-flow cat on the Sti, so that should help it a little...

 

I bet chronohunter (Paul Gerard) has.

I think that the point that the somewhat soft springs being overdamped is a pretty well accepted fact. How far you would want to go with springs on the stock dampers is up for debate.

Where can you buy the Ralliart springs? When I looked a while ago I could not find them.

 

Your best bet for Ralliart springs is to contact Gruppe-s (www.gruppe-s.com) or Adam @ Z1performance (www.z1auto.com) ...
