HELL YEAH! :headbang:

Another Shelby/BMR min drop combo...now I don't feel like the only crazy one :cheers:

You'll enjoy it, trust me. Looking forward to hearing your experiences and review. Don't get discouraged, mine took about 2 weeks to break-in.

How do the GT350R springs compare to the BMR front's SP088 right?

The direct comparison front spring is the SP084, which is 300 lb/in vs. 240 lb/in for the GT350R front. The R front spring is also a 3/4" drop vs. 1.2" drop for the SP084.

So with the Black Friday deals and all I decided to wait on the install and get camber plates and the rear alignment bushings since I'll be back there. So the plan is to install this coming weekend.

Has anybody ended up installing GT350R front and the two left rear GT350/R springs?

If so, please share your thoughts of the install, what shocks you paired it with, driving impressions and photos!
Cheers,

Cheers,
R and non-R rears are different p/n and apparently a bit different rate from Vorshlag's testing (see previous page).

R fronts and non-R or BMR SP085 rears with FRPP Track dampers is my current plan after winter. The SP084's just drop the front too much for my needs.

Thanks. It seems we dont have anyone here who has done front and rear 350R springs yet. Hopefully that will change soon. Otherwise I will probably do the same as you Bmac in spring and pair with FRPP dampers or Steeda Pro Action (unless we hear from others). I was considering Koni Yellows, but based on what I'm hearing I know I will hate the compression damping.

Yeah I know what you mean on the Konis. Based on [MENTION=26233]Rebellion[/MENTION]'s feedback on the R fronts and SP085 rears paired with the FRPP dampers, it works quite well for significantly improved handling without making it too harsh for daily driving (and actually improving the composure over most road imperfections).

I'm starting to think I should have went with this setup. I just bought BMR 082/089 springs and planning to grab Steeda adjustables today.

You'll be very happy with the 089/082 setup, especially considering your goals.

Alrighty so I got this installed over the weekend. All I can say is, is that I am over the moon happy with how everything came out. It feels like a true sports car. I do not know how else to explain it. Less nose dive, smoother transitions, better turn in, it's all there and its all great. This is how these cars should feel. I was a little afraid it would be a little rough and harsh and it would be something I would have to live with. This is not the case. And let me tell you...our roads are absolutely terrible. My daily route is filled with bad roads, bumps, cracks, holes, bad patch work, etc. (especially on the interstate and in my neighborhood). I don't want to say it soaks up the bumps as it sounds like something a crownvics suspension does but that's essentially what it does. It stays so composed over the road and imperfections. To me, the compression and rebound is perfect with this setup. It all works together. Reminds me a lot of when I had the Greanleafprime GT500 setup on my first 07'. It just all simply works together.

I have the Black Accent package with the 19" wheels and it sits perfectly. Once it all settled, it looks fantastic. Forgot to get the before and after measurements, sorry about that. You can definitely tell the drop brought out some more camber in the rear. The front was easy with the camber plates. My gauge shows I now have about -2.4 in the rear. Up from the -1.5ish from factory. I'll be bringing it back a little this weekend hopefully.

The install was pretty straight forward coming from the S197's. Man those front strut/knuckle bolts are in there good. Took a many a whacks from the mini sledge to get it out. And those front springs are uber long. Light weight but really long. Since it was my first time working with the IRS, I didn't get any pics from doing the rears since I was concentrating on doing everything correctly. It was funny to see how the base shock has a larger shaft then the PP one but oh man let me tell ya. The compression/rebound on the PP is definitely far greater. Took my entire weight on the shock to start to bring it down to put it back up in the rear mount. Oh yea...I was pretty frustrated to see that the new front struts didn't come with the bottom spring isolators. I ended up having to take apart my stock struts. Wasn't really a big deal, was just trying to avoid it to make an easy swap.

Got late during the install and our weather is craecrae out here right now. We'll have upper 30-40's at night and then like today will be 78, with rain and humid and muggy as fack. I'll have to get some good photos this weekend.
