Hello All,

As some of you know I have been interested in finding out some more info on the APEX coil overs that TRi and a few others sell.
From my various surfing and reading, I think that the struts themselves are made by Koni to APEX specs, and the springs are made by APEX, since they are a spring manufacturer. The spring rates that come on the struts aaare pretty soft for tarmac competition use, and they are 60mm ID springs, so Eibach and Hypercoils don't make anything to fit, at least not to sell in the US. As a matter of fact the only people that sell 60mm ID springs here are H&R and Apex. APEX tells me they only sell the kits whole, and will not ship struts without springs, and that they cannot offer any with cusom spring rates until much later in 02. So, to make a short story long, I will not be getting this coil over settup, due to the fact that I really want to be on a good set of coil overs for race use by the beginning of the next autocross season. I do think that these are probably a great buy. 22 way adjustable, aluminum bodies manufactured by Koni, and they can be had for about $1250 a set.

The standard springs are around 200 lbs/inch. That is a close as the gave me.

Do you know what stock is? Eibach used my car to develop a ready to go race setup that never went into production. They told me that the springs they used were barely firmer than stock. Valving is what makes them stiff.

Yes, but valving along with proper spring rates for the valving are what truly make a suspension perform. The APEX would need, according to them, higher spring rates to be a top notch autocross suspension. In there words, the stock spring rate is for street use.
