Divine, if the kit uses stock length shocks, the springs better be stiff if you want to go LOW (2.5"+) if they aren't you will be bouncing off the bump stops of the shocks, perhaps eventually blowing them out. When you drop it LOW you are reducing the amount of shock travel right from the start. Soft springs = more shock travel. Hard springs = less shock travel. To go LOW and still have shock travel, GC uses a shorter shock insert, so you can cut the struts down an inch or so. You can't do this with stock length front shocks. This along with coilovers in front will allow you to dump the car while still having some suspension travel, at least enough to work properly.

Thanks for breaking it down for me... much appreciated...

We'll see when I can get 'em on. At $380, it's not a huge hit if they blow. From the reviews I've read, they are a cheap alternative to get a bit low and have some adjustability. They are most definately not a track suspension, but I'm not going to the track.

Yea it would be nice to still have the option to track, but it's a cheap alternative and will help lower my front end a little bit more than it is now. I'm not trying to dump it too much, just enough to reduce the rake and still have some adjustability options... for that price I'll make it work... We get what we pay for but this should work fine for me... hope to get mine soon...

this was cheaper than buying just a standard H&R Race setup for the S50 project. I need a bit stiffer than H&R could give me.

But the springs rates are no where close to the Races. It's not like the JOM kit came with quality dampers either.

[ck_taft325is]

Good news is, I don't plan on slamming by any means. A bit of adjustability and mild low for DD. The spring rates, while not as stiff as they could be, are not bad for daily driving status and for me personally, this was cheaper than buying just a standard H&R Race setup for the S50 project. I need a bit stiffer than H&R could give me.

Anyone low without modified strut housings is riding on their stops. End of story.

unless they have camber plates that add travel or shorter bumpstops..

The shorter strut inserts are what necessitate shortening the housings. You can't just chop 2" out of your strut tube and drop a normal e30 Bilstein strut in there.

But yes, if you're going more than 2" down, you're asking for trouble.

We have Bilsteins and coilovers on our LeMons car, and it probably won't sit more than an inch or two below stock. All the way down on those and it's straight up bottomed out on the bump stop.

Most likely will have to cut the perches and shorten the tube a bit.

With the supplied stock-length inserts? LOL, make sure you post pictures whilst attempting this.

yo mah bad. i had gotten mine on tuesday, just havnt been online. the whole kit itself is clean, but springs dont seem to be as stiff as i planned. My o2 sense, dont slam the car. Shocks will eventually blow. Most likely will have to cut the perches and shorten the tube a bit.

Which springs did you get, Erik? I contacted via E-mail for the heavier duty "cabrio" springs which according to them, are considerably stiffer.

I guess I got the regular "coupe" springs. I didn't think there would be a large difference in spring rates between the two.

^^ Oo0oo The suspense! Its killing me!

I'm going to hold off before I say the line.

[erik325i]

Erik, did you measure the spring rates yourself or ?? how to did figure they were too soft?

I don't have a spring rate tester, so I can't tell you the exact rates, but just by putting my weight (~175 lbs) on the spring, it compresses close to an inch and a half.

[reelizmpro]

can someone speak in lame mans terms... sorry I'm still learning... school me on bump stops? Does that mean the will basically be at the lowest position sitting on the part which prevents the car from dropping down any lower when it hits a bump?

If so the ride will be very stiff and hard yes? I don't know please explain... thanks.
