AGX + springs

[Watazz]

Does anyone know of a good spring to go with the KYB AGX's? Preferably a lowering spring. I may go with QA1's in the rear.

Sam Strano. It is matched to the shock. The shock wants no more than an inch and a quarter lower, and that is what sam offers. I love them!

I went with Hotchkis. The general consensus for overall best spring is Hotchkis if you want progressive rate and Strano if you want linear springs. Both lower the car about 1-1.25".

I went with the Hotchkis springs also and then installed the KYB AGX's.
The car rides very nice. My front end is up a little higher than the back but that's because of all the weight reductions I did in the front.

Re: AGX + springs

Like said above, strano or hotchkis, hotchkis being a progressive rate, will be a little more forgiving on your back then stranos will, but for the best handling, go strano.

Re: AGX + springs

It's unlikely that Hotchkiss makes springs. They probably buy them from a spring supplier. Hotchkiss springs are no better or worse than many of the other popularly-priced aftermarket suspension parts.

If you want the best springs, look at Eibach. All Eibach makes is springs. They have fabulous engineering. Ebiach products are used world-wide in motorsports such as F1, Sprint Cup, Indy cars and AMLS and are also used by some high-end O.E. applications.

As for the progressive rate vs constant rate rear spring issue...F-cars have progressive rate rear springs so the car has a nice ride when lightly loaded. From a performance handling standpoint, at normal ride height, the rear is somewhat under sprung. Best for handing are constant rate rear springs. Admittedly, with them, you trade some ride quality at normal rear height for better handing.

On my THRS project car, I run QA1 coil over shocks in the front with 600 lb/in Eibach springs. In the back I run QA1s and Global West 200 lb/in constant rate springs.

Re: AGX + springs

Have fun wit your eibachs when the rear sags in a couple years. I went with kyb agx and strano.

Re: AGX + springs

My Eibachs held up fine for 13 years then had to replace them with QA-1's all around , 300 front, and 1le's in the rear.

Re: AGX + springs

I just installed AGX + Hotchis springs and I love them. Firm up the ride and IMO make the care more balanced. I run them set at 4 front and rear and the car drives like its on rails. I may suggest a set of spacers in the rear to keep the car level with its original stance because my bird dropped about 1/4 to 1/2" more in the rear then the nose but that may also be due to the sub and amp in the tail. Aside from that They are worth the price by far. The progressive springs give you a firm but tolerable feel over normal road conditions but you still get that tight response from the higher rates when you throw it around.
