BMR lowering springs.

Nope wasn't me but i did just order a Cyber Monday deal on a crossmember for a 4L80 conversion on my car and had a few questions via email. I will post pics. The eibachs sit nicely but when i hit a bump they bottom out. I'm running 315's on Billet Specialties w/ rolled fenders and it sucks hitting bumps with the Eibachs. I'm guessing the fronts won't be much different but i suspect i will notice a huge difference in the rear due to the sagging crap Eibachs. I would be perfectly fine if the car even sat marginally higher if it meant not bottoming out the rear on bumps. I will post pics for you when i get them in. If you look in my sig you can actually see the rears sit slightly lower than the front... it's annoying. The car currently has a BMR strut brace, BMR relocation brackets, subframe connectors, will have BMR crossmember and BMR panhard bar. I'm also looking at a BMR torque arm from a local guy. The only thing NOT BMR are my LCA's but the previous owner threw them in with the car and they are Spohn adjustables. Now i'll have BMR springs. You could say i like my BMR stuff

I believe it was me you were speaking with. I pulled the trigger on the koni's but not the springs. I want to see the difference with the koni's in and I'm going to swap the rear springs to see if its a sag issue before I purchase new springs. I'm likely going to do springs anyways and should have just purchased them at 15% off when I could. Is that your last sale of the year or when would your next sale come around? I like the stiffer springs conpared to the eibach ones I have now. Hope the car would be slightly higher also.
Cole.... I will be looking forward to your before and after pics...mainly after as I'm on the eibach springs now which came with the car.

Here is just BMR springs and Koni shocks
I am now on the koni lower perch and the HH mod in the rear. For wheel well measurements:
Front:
Ground to top of wheel well 26"
Ground to front rocker 5.25"
Rear:
Ground to top of wheel well 26.5"
Ground to front rocker 5.5"
The bottom of my stock K member is about 3" off the ground. Here's a couple pics. These pictures and measurements are from when I first took it off the lift.
It has settled since and I have maybe a one finger gap in the front and 1-1.5 in the rear. I can take some pics if needbe. It's pretty low. But it looks nasty since it is so wide. My sig shows how it sits now but it's kind of hard to see.

Update. The i've only done the rear springs so far as they were the easiest to do. The BMR sit about 1/4-1/2" higher than the Eibachs that were in it but that is likely due to the sagging of the Eicrap. When i pulled them out and pushed them down they compressed far easier and further than the BMR's did. I expected this as my Eibachs were bad. They bottomed out and hit when you went over bigger bumps and just felt too soft. I haven't had the BMR's out yet but i suspect they'll ride a little more rough but i can't say for sure.
Eibachs(sagging) notice the rears
BMR rears. They sit a little higher but i'm fine with that as long as they don't hit when going over bumps

I've got the same issue Cole... Sagging prokit... plan on taking advantage of some new shocks with 50% off springs from BMR most likely before its over to replace some crappy KYB's and Eibach's...Should have done it right the first time

The front Eibachs aren't supposed to have the same issue the rears do so i haven't bought the fronts yet. Plus i HATE dealing with compressing the springs to get them off the struts. That **** makes me nervous because if they come off the clamps they could kill i actually wrap my spring in a rug as i compress the spring just in case it takes off but even then i'm nervous as hell

Does anybody who went with the BMR springs suggest going with the Lowering Spring Package, which includes the Adjustable Panhard Rod and the Control Arm Relocation Brackets? I know I'm going with the BMR springs for my 2000 SS, but saw this package offered on their site. Thanks for any help!
From their site -
Adjustable Panhard Rod - Since the F-Body chassis is equipped with a panhard rod to locate the rear end in the chassis, altering ride height can shift the rearend to the drivers' side up to 3/8". This not only effects alignment but can create tire clearance issues as well. To properly re-center the rearend, an adjustable panhard rod is necessary. Equipped with grease fluted high durometer polyurethane bushings.
Control Arm Relocation Brackets - Lowering an F-Body changes the rear control arm angles, altering the vehicles "instant center" location. This instant center is the virtual lift point of the suspension and is responsible for initiating weight transfer upon acceleration. Relocating the control arm mounts on the rearend re-gains and improves upon the original geometry.

Right now we are also offering a special on 4th gen Springs and Koni shocks.
