I would get SLPs because I like the way they fit and you don't lose as much ground clearance as boxed BMRs. But I bought BMRs because I had concerns about the SLPs fitting my car since a previous owner had been in an accident and I don't know how straight the car actually is. I've heard that they're heavy, though, and I don't know if they're powdercoated. BMRs are and I think that's the only way to go.

 

Here's what I can tell you from my experience...

My car has 164,000 miles on it. It's a daily driver and my autocross car. It gets abused. I don't have subframe connectors (class won't allow it) and my car doesn't rattle, the t-tops don't leak, my dash isn't falling off, my windshield hasn't cracked....

Will it help make the car FEEL better?? Yes. Will they help to keep all of these terrible things from happening to your car... not in my experience.

 

My slps only lost me about an inch, but really it jsut made it as low as everything else.

Didnt wieght much, maybe 50 lbs for both.

Thinking more, they are what Iwill be buying again.

 

SFC's will certainly help ANY unibody car, and are a must prior to any major performance drivetrain mods. The best bet is usually to go with weld-in, but the bolt-in ones are generally OK for mild street use.

I built my own custom tubular SFC's (bolt-in) for my '79 camaro. I don't race it, but just wanted to improve the handling, eliminate sag, and stiffen it up a little. What a difference! This design could be even stronger if welded in place. No more squeaks and rattles, and you can feel the difference right away. Check it out at http://pound94.sytes.net The 2nd gen design should be fairly easily adaptable to 3rd or 4th gen. just take your own measurements, check often, and weld carefully. They cost me about $25 in material and mounting hardware. I will update the drawings and installation pictures when I get a chance....
