Springs? I have Racing Beat springs all the way around, for a modest 1-inch drop. I have also used a Ground Control coil-over front suspension with their specially wound dead-coil rear springs (there are several "dead" coils that can be cut off without affecting the rate).

I'll be honest i have no idea why it wouldn't be a good idea, but more that i've never seen any solid axle front or rear ends use a coilover setup. The coilover setup has it's advantage in inpendant suspension systems. I believe it has a lot to do with how the axle moves up and down as a unit etc...

coilovers:

This is on an ex two times Danish Championship Roadrace FB so I'd say it works pretty well. This was originally posted in Race Car Tech by Kim. I also believe that 680RWHP has coilovers in the rear as well except his car is build for drag so it is probably significantly different. If you are running in a class with few rules then this would probably be an excellent set-up, but waaay overkill on the road.

The only reason I know of for not using coil overs is that a shock mount is not as sturdy. So if you have a rusted body you may send the coil-over right through the body.
Also if you're getting bouncieness with cut springs it prbably just means your shocks are no longer set up for the new range of motion of that spring.

Grantmac, thanks for the link! That was a tight setup with the coilovers and the panhard. Then Panhard has been on my mind for about 6 months and this was the best pics I have seen on a install.

Well that panhard is kinda screwed up. Keep in mind that this isn't my car. There is a pretty good discussion of that rear-end set-up in the Race Car Tech under "I just bought a 13B PP racecar" or something like that. It may actually be an equal-length watts link that you're looking at.

Only reason that comes to my mind for not using a solid axle with coilovers is the "GM Effect". In the 60's GM built several cars with coilovers and solid axles. They had this strange habit of "floating" the car out from on top of the axle in cornering, resulting in the axle whipping back into place.
Subsequently they are my grandfather's choice for a drift car. He maintains that RX-7s and 240SXs are far too small and nimble to be good for drifting, and that his 60 Cadillac convertible was the ideal drift car because it had the above mentioned suspension.

G-force engineering "red dot" rears springs will slam the back and ground control coil-overs for the front with eibach race springs. thats all you need. i'll get pics of mine hopefully in the next couple of weeks to show you

Mine's lower, by a LOT (probably about an inch, maybe an inch.5), than the other RX 7s around town. It has KYB shocks and god knows what else. I can dig trhough the receipts if nothing else.

How nessesary is using the racing beat front lowereing kit (the kit that welds to the top of the strut towers) when using coil overs. I want a good drop but really don't want to cut out my strut towers. Will the shocks bottom out without using this?
