can someone give me some input...im thinkin about the racing beat convert springs but not sure what to get!!!!

 

On mazdatrix's website, they say they tested them all, and list the rear springs as being softer than stock, while the fronts are harder. To me, this seems to be setting the car up to understeer more, which I dont really understand, especially when the rear of the vert is heavier than the coupes, yet the coupes rear springs are stiffer

 

I have a similiar dilema. I bought some KYB AGX shocks/struts for my 90 vert and have yet to decide on what spring to go with. I've read plenty of info on this board and if anything I'm probably more confused and overwhelmed ! I'm leaning towards the Racing Beat vert springs, but opinions on this board are like you know whats... It's all a matter of personal preference I suppose and how you intend to use the vehicle.

 

I'd get coupe springs because I prefer 1" drop. Because of weight reduction done on my vert, I am expecting it's at least in stock TII weight range thus coupe springs are just fine.

 

A certain track type person told me to keep the stock springs and just put AGX shocks on mine. I would want at least the same as stock when new or better if I were to replace them. Like NC said it's a matter of preference and what you're doing or going to do with the car.

 

Rotary Performance in Texas used to carry a complete suspension package that included Tokico Illumina adjustable shocks and progressive springs. I put those on my car in its 2-rotor days. It lowered the car approximately 1 3/4", gave superb handling on the track and was very comfortable when driving on the street. On the track it would let me eat stock 3rd gens through the curves.

If you have a non-stock nose on the car or an aero kit, you may find that the car sits too low for street use, though. I had to switch to Ground Control coilovers to raise the car after doing the 20B conversion and adding the Mariah Mode I nose.

 

There's only ONE RX-7 Vert Specific Spring manufacturer, that's Racing Beat. Don't bother putting the coupe springs on your vert.

BTW - don't forget when lowering the car you need to correct allignment with more adjustable components. The front tires will allign by turning the strut tops 45 or 90 degrees. The rears require aftermarket components. The best way are AWR's camber links sold through Mazdatrix:

You can go with Racing Beat's more affordable camber adjuster, but it requires some modification to the floorpan to give the subframe-rear A arm links more clearance.

If you just bolt the lowering springs as is, you won't notice any vibration, noise, or additional tire wear from the resulting mis-allignment, but the car will handle a bit strangely while cornering on bumpy roads. You'll probably also loose a bit of grip.
