(you really need vertical compliance and stiff bars to control the roll)

I agree I has H&R's and Tokiko's and with the streets here the ride is horrible, it does handle half ok though. Still need to get sway bars and replace bushings if i keep my car.

The Nylon Bushings cost more but are very good if you are going to be pushing your car really hard.

Handling is relative. Having owned both a modded MK2 Mr2 and a mk3, I can tell you without a doubt that the mk3 will never be as good of an autocross car as the mr2. But even in stock form, the mk3 supra blows the doors off a street prepared mr2 on real roads once you get over 100mph.

When gutted with coilovers and chassic bracing, my mk3 supra could keep up with my mr2 in 30-45mph corners (and surpass the mr2 at anything faster), but it was definitely out of its element under 30mph...

read this first on shocks

There is also good info on Dr. J's site, mkiiitech.com, under suspension and auto-x.

Hot dam, someone on here has also read DG's info on good competition shocks, now where do we get a Bilstein setup made? I've been trying to do that for a while.

You've certainly got to make relative comparisons, it's not a 2200lb. car, the wheels on that MR2 are big for the weight, short wheel base so quicker transition (how often do you spin it on course, a longer wheelbase spins less easily) It's a heavy car, make sure the suspension is in good shape (all that weight has been hard on it over the years)

No one's mentioned the Tanabe bars. I run a ST rear and Tanabe front (had massive oversteer so swapped to a stiffer front bar, now very close to nuetral) The bar is much lighter than the ST front bar. I think the best aspect my car has is it's slalom ability. Hard corners aren't great (Tokico and Eibach for now :( ) but I'll try to improve that. I also use wide wheels for the tire sizes 235/255 on 9/10" widths.

FWIW, there's a link in the racing section of my last event. Best finish so far, just behind a 93 turbo MR2 running R' tires. I've just stepped up to Azenis. For some reason I've done better in my 1.5 years autox-ing on smaller courses, I think it's because its easy to drive the Supra with the pedals :)

It's a blast on the track too just heavy for some auto-x courses where the V8's have instant torque and small cars don't have to lift where we have to.

I just installed Tanabe front & rear sway bars and weighed stock and Tanabe for comparison. There wasn't much difference in weight on the rear bars but the front Tanabe bar is much lighter than stock. See for yourself . . .

I tried to balance both as best as I could without grasping the bars so I wouldn't alter readings. I made multiple attempts to weigh both and consistently got the numbers in the pictures. My readings should be very close. There is an obvious weight difference in the stock solid bar and hollow Tanabe bar just by holding each side by side.

You wasn't holding onto the sway bar very much when you were balancing on the scale was you?

That's cool. I'm surprised the aftermarket bar is lighter. It usually takes a heavier, solid bar to make it stiffer, but I guess it depends on the materials used...

I know that Bilstein will valve them: http://www.bilstein.com/services.php
if you have an idea of how you wanted them changed. Most of the other builders that I have looked at are either porsche or ferrari specialist, so they are a bit pricey.

I almost bought a set of bilsteins, but bought the Koni's instead (before I read DG's reviews) and know exactly what he is talking about when it comes to getting the adjustments matched by the seat of the pants...its impossible.

Now what to do about springs? I guess if you are going custom valved, you would know what type of spring you would want already or atleast have an idea. I can't help you much on that one as my change to koni's was an attempt to improve the ride from the previous set-up I was using.

Material used for Tanabe stabilizers, taken from their site:

Chromemoly is extremely lightweight and rigid, when compared to heavier standard steel, which requires more material to achieve the same amount of strength. Chromemoly steel is commonly used to build roll cages, and has an established reputation in the performance community as a choice material for a reasonable price. Sustec Stabilizer is extremely lightweight, and is engineered to provide the favored neutral balance, which can eliminate factory suspension settings for understeer.


The Tanabe bars are definitely stiffer than stock .. I can vouch for that! Their lighter weight compared to stock is a bonus.
