A list of MKIII spring rates OEM, aftermarket and coilover

[tErbo b00st]

Anyone know anything about the bilstein coilovers? They came with the supra I just bought. All I know is they are "old school".

Nice coilovers, but they are a little on the soft side imo.

Yeah, I have some Trust coilovers I'd like some info on too. Here's a scan from Hyper Rev

I have their full coilovers. That looks like just dampers. And they are blue too.

Sure Tokiko claimed 415lb/in front and 199lb/in in the rear, but the set I measured was different. I measured 428 & 396 for the fronts and 190 and 219 for the rears. Sure, they average out... I'm surprised/annoyed at the spread. The stiffer one went on the driver's side.

The 2 TRD fronts I measured came in at 450 and 436lb/in. I didn't have any rears to check at the time.

I'd love to have someone measure some stock springs. I can't believe the numbers presented here. I'd guess they're more like 375/180 F/R.

The method I used was a tape measure, a hydraulic press, and a corner weight scale. Compress the spring 1" below free, zero the scale, then compress 1". It has given good results for springs like Hyperco, that I trust come with accurate rate specs.

Quality springs should never sag. If yours sag, send them back for replacements, because they're defective.

That actually makes sense to have the slightly firmer coils on the drivers side as thats where usually the driver sits! This helps even things out with the rest of the car as the drivers side would normally be carrying more of the weight compared to the passanger side.

Any one have the specs on the JZA70? Im looking to get those as a slight drop
