So I did a search and for some reason didn't come up with much. If i still daily drive my FD and want to have some weekend fun doing auto X, what suspension set up do you guys recommend?

 

Unless you are serious about the autox, just run whatever is on it now.

It will still be fun.

 

Stock touring edition.

only the first post or page needs to be read. if you want a dual purpose car, the setup outlined at the beginning is a great start.

 

Ah, good read. Having come off of Miatas, I knew Mazda had good suspention, but the FD seems likes its pretty much set up from the factory. From the sound of it all I need is Eibach Pro Kit and stock shocks. Glad I read this I probably would have spent to much on suspension that wouldn't really have helped.

 

I think the koni sport shocks are a nice step up from stock. I run mine full soft during the week, and notably stiffer for the autocross.

 

Had Koni's on my Supra. They weren't to bad

 

yeah its pretty good right out of the box, in fact you get most of the way there with an alignment

the pro kit springs are 6.9/4.9 kg/mm front and 5.1/4.0 kg/mm rear and 248mm long in the front and 262mm long in the rear

 

Are the Eibachs Linear or Progressive spring rates? I don't remember....

 

since they give two rates i'm going to say progressive.

 

For street/autox there is no substitute

Tein Flex Coilovers

At this time there is no reason to ever consider koni yellows, tokicos or any cheap shock spring combo when good coilovers can be found for 1500.

 

They are linear.

The Eibach's are ok performance wise. The down side to them is the look they provide the car. The Eibach's lower the front by a little over an inch, but basically nothing in the rear. It creates a fairly large rake which is the opposite of what most FD owners want for the look of their car.

I had them for a number of years and tracked them as well. Street comfort was good and track performance was decent. However, I would recommend the H&R Springs instead of the Eibach's. The H&R's are progressive but perform well at the track. I know several guys who used the H&R's with Koni's running r-comps. The H&R's also give the car a real aggressive stance which is nice as well.

If you have the cash, Fritz's suggestion is the best to go with. If you are even considering coilovers down the line, just save up now and do it rather than purchasing something now which you aren't going to keep in the long run.

 

Good to know. I H&R's on my Miata with KYB AGX'x

 

Just to toss in another choice......GROUND CONTROL. Adjustable height, springs available in different rates, and you choose the shocks. Good quality and IMO reasonably priced.

what spring rates do the GC coils come with ?

 

in my experience i dont see a reason to stray away from ground control and a revalved shock for your spring rates until you think you need to spend 4k+ on your set up

 

From what I'm reading it sounds like you're right.

 

IIRC, 550/450 f/r

 

I really like my greddy s-types. People comment on how well it soaks up bumps all the time and they served me well at the dragon.

 

Depending on diameter, pretty much any rate you want F/R. You can customize depending on use. Available rates are on their site.

 

Get some adjustable coilover.

The Gc coil over conversion seems kinda ghetto, why spend 600 on that when you can get full coil overs for a few hundred more

 

because the GC stuff allows you to use a good shock, and that is the important part.

 

GC is probably THE MOST popular suspension found on track every weekend. spec miatas come to mind here.

fatcat motorsports has a package for autox/ street miatas with revalved bilsteins for $1500ish. ride quality is extremely good, even over expansion joints on the interstate that get bumpy.

i wish someone sold a similiar package for FD's as it is hard to beat this kind of custom set up vs. a mass produced coilover that offers good ride quality but sacrifices spring rates because their shocks wont handle the stiffer spring.

in my opinion on adjustable shocks, is only the high dollar ones offer the most reward for your fine tuning. anything else only offers 16 clicks between stiff and squishy.

 

This is what I'm currently running. And also my experience. Good performance that doesn't make your teeth rattle on the street.
Is GC the absolute BEST of you can get? No. But components are quality and a damn good value IMO for those (like me) who need the compromise. Ghetto? Nonsense. I've had them for years and they work. Have a friend with a serious single turbo FD that's tracked frequently who's been happy too.

 

With the Ground Control - Coilover Conversion kit, 93- Mazda RX7 coil over adapters you can't adjust pre load and ride height separately, with coil-overs you can.

I have Apexi coil overs on my car, soooo much better than stock or aftermarket spring/shock combos.
