Bill,

The sportlines are not the best for handling, they are not even very good for it. The problem is that they are too low and have too little spring rate. The Eibach Pro kit is a better choice than the sportlines. I'm currently running H&R's and I autocross my car as well. The front rate is fine, the rear may or may not be a little stiff (I think it's ok) the rates are 600+/200+ in lbs (F/R). You'll need good shocks to damp them though. Or, just look into the ground control kit. You can get any spring rate you like. Many (most?) autocrossers are using a 500 or a 600 in lb front spring and a 150 in lb rear spring (with a few exception). That is an excellent way to go, but it's more expensive than a standard lowering spring kit. Either way, I'd ditch the sportlines (you should have no problem selling them to the show car crowd around here, they love those things).

Also, I think LG is doing a GP on the G2 springs right now. They are a little softer than the H&R's but stiffer than a pro kit.

Another vote for H&R here, I have used them on three of the four 4th Gens that I have owened and will be making it four for four here shortly. They are a great spring that is tame for the most part on the street but give a great feel when called upon.

What about them? I run H&R exclusively and one time Trackbird said something that was very true about spring selection. Why go with a company that does many different products when there is a company DEDICATED to nothing BUT springs? That is quite true when you think about it. Not to say that they make a bad product but all their attention can't be focused on one goal. Also, many companies have someone else coil their springs for them if they don't have the means to do it themselves. You would have to know all the angles to make a truly informed decision. Having a heritage in the type of racing you are making your setup for can't hurt either. Auto-X suspension drivers/builders vs. drag drivers/builders. Hope that helps.

That's really the key point. I have no problem with buying a part that is designed/specified by someone who knows what they are doing and outsourced for fabrication to a suitable shop. For example, the Strano hollow swaybars, LG/G2 Super Springs, various Unbalanced Engineering parts, etc.

OTOH, if the designer doesn't understand the application ....

The BMR springs may very well be quality parts (dunno), but some of their other designs don't really demonstrate a grasp on cornering.

so how much of a drop do you recommend with the H&R's for a daily driven /ESP car?

It's not about "the drop", but about the spring rate ...

thanks for not really answering the question. I know it's more about the spring rate.

Hey Mr. Furious , Do you always **** on peoples boots?

Your drop is none adjustable. It varies, my car lowered about an inch . I've seen other with the same spring lowered about 1.5 inches.

any spring that suits your spring rate... but as linear as possible... progressive will make your life miserable on shock damping.

Good stuff. I've got an 02 SS with the Bilstein susp. They are progressive and while they may ride nice on the freeway, they suck in autoX. I've bottomed out the rear once and it was not pretty (Houston we have lift off).

Will the HRs work well with the Bilstien shocks?

While stance doesn't help the handling, it does make a difference when you look at your car.My SLP setup has the *** dragging and the front in the air. What kind of stance will the HR give me?

is there a website or post where I can learn more about them?

I got talked out of ordereing the 1Le by poeple saying it's too harsh!!! I wish I would have gone for it now!!!

Like what exactly? I'm looking into Boxed LCAs, Tranny Mounted Adj, T/A, Adj. PHR, STB, 1LE sways, and some SLP SFC's-and i was planning on BMR Springs w/ QA1 or Bilstein Shocks...

Is anything wrong w/ that setup for all around handling and daily drivability? is something there not worth it at all? I really wouldn't know, I'm looking for Road Course, AutoX, Drag Race, and Daily Driving setup.

qa1 are drag shocks, not good for any of the above if i'm not mistaken.
