progressive springs work good if your autocrossing your daily driver but if your going to be serius there not the way to go
Dude NO no they DON'T work in an A70 fullstop..... :aigo:

They work ok in a Mac Strut front end but the double wishbone system we use blows through the lighter rate section at the slightest bump or direction change and all they do is add to the body roll..

SG05: I use a set of Eibach straight wounds on custom Koni Coilovers I had built.

man how many times do i have to say this KONIS HAVE A LIFETIME WARRANTY TOO

I'm aware, but they rebuild them and have a horrible turnaround time..

Have a friend that autocrosses and run konis and eventually bought 2 sets as they kept failing and the turnaround time was over a month...

bilstein, you walk into a dealer and they are replaced on the spot if they carry them...

decisions... decisions... so, for what i want to do, stay away from Eibach. what are the stiffest spring availible for our cars? and, to find a damper to handle it, thats the question.

Used to have a link somewhere to a table that listed the most common spring rates.
H&R, Intrax, Eibach, B&G, RSR, ST, Tanabe, TRD, ect...
Maybe someone can dig it up.

How exactly is that soft?

We all know coilovers beat any springs, but a good spring is a nice ride.

This is what I have. I prefer not to feel every bump on the road.

How are they soft huh? Well.... try drifting with them, and then when your slides are killed my the massive amount of body roll the allow, then you'll know how it is deemed "soft". Supras are VERY heavy and if you want to road race or autocross you need a hard spring. The megans I got are 18kg front springs and 14kg rear. My rears are harder than the RSR fronts. I may still need them to be harder all around though. Maybe, i haven't exceeded their limits yet. Only NASA will tell.
But i guess thats where our differences are, where i want pure performance for ultimate handling instead of ride comfort. You just have to realize if you're going with a spring like that, then dont expect to really be competitive when it comes to these events. Unless its with other weekend warriors that have the same needs

PS- I'm not dissin the RSR's because i almost went with them myself awhile back, i just find it funny they call them "RACE SPRINGS" when i dont think any real race Supra would use them based on their rate

Apparantly i do both, i believe i said this

And i also mentioned how our needs are different, i dont daily drive mine so i need all the pure performance i can get. But have you actually road raced on those, i mean like time trial or HPDE?

So you're really trying to claim there's absolutely no roads in this big ass state we live in that could possible test the limits of your suspension? ;)
So the answer is no I have not, yet.

As I also mentioned he's not drifting. It also doesn't appear he wants the hardest suspension on the planet know what I mean??
Hard is best for drifting no doubt, but unless he plans on going crazy all week, that kind of setup isn't really necessary.

Well the heavily pitted potholed roads of Calistoga aren't really similar to Infineon Raceway. Like how i mentioned my car stays strictly to the track so i dont drive it on streets around here.

I also know he's not drifting, and i believe i said this about autocrossing and road racing

If its just for fun no prob. but once again, back to competition. I dont know if he's looking to be competitive or just wants to have fun in his own car.

i'll some day be real competitive with my car but thats from now. like i said before, i'm just weighing my options. i know a good set of coil-overs are far more superior than any spring/damper combo. i just wanted to get peoples opinion on what would be the best spring/damper combo... if i had to go that route. of the different spring manufactures, who produces the highest spring rate and liniar performance? also, of the shock and strut manufactures, who produces the best performing product? i know everyones needs are different but lets break it down to road course racing (T/A, AutoX) and drifting.

bilstein arguably makes the best performing dampener (and you won't need springs to lower the car, the shock has different height levels built in)

The only reason I'm looking at coilovers is because they'll give me a stiff enough spring without losing ground clearance (I'd like to keep a stock ride height)

One thing I haven't seen mentioned is the need for the Shocks and Springs to work as a matched pair......

No use using a stiff spring if the damper can't match it.

When I had mine built they were tuned on a shock dyno and on 0 are just right for daily driving, for +150 mph I cranked a 1/4 turn into them and they're perfect.

true, but we can't all be so rich :D

This is why a good NAMEBRAND coilover works, as they have the springs and dampeners matched...

I love Bilstein dampers, but not so much for their off the shelf damping more so for what you can do with them once you open them up. They're the most cost effective solution to a problem.

But likw IJ said, you need the dampers to match the springs and the weight of the car if you want the best setup. You can take an off the shelf damper and pair it with some random lowering springs and it may or not may work as planned.

Depending on what springs and dampers you use, you could have much better performance than a lot of the coilovers on the market right now. Most of the valving on those dampers isn't that great. They screw up the compression curve to make the car feel stiffer but that also kills ride quality and then rebound is usually off too and in extreme cases can lead to jacking down over a series of bumps. But I guess they do give you stiff springs and you can slam the car if you want so if that's all you're looking for then entry level coilovers will work for you.

I also have some problems with the rates that some of the lowering springs or coilovers come with. They don't help the balance of the car as much as they should and in some cases they make it worse. Too stiff of rear springs in relation to fronts and your car will be too loose. Too stiff in the front and it will push. I mean I've run all the numbers and designed my own setup, so I've put a lot of time and R&D into the supra suspension already.

It really depends on what you want to do with the car and where you want to cut corners. It seems that a lot of people will go all out with their engine setups and then don't want to spend more than a couple hundred on a suspension setup.
