GT with 305/35/20 NT555R DRs, I think I need new rear springs...

[sleeper02]

So the suspension setup is as follows:

BMR Sport springs (1.5")
Koni Yellows
BMR UCA/LCA
BMR RLB
BMR PHB

The wheels and tires:
20x9.5 +35mm
305/35/20 NT555R

The springs are settled so I think its more of a 1.6 -1.7 drop now, and I'm looking to raise the rear. I recently installed a VMP TVS and she's going to squat and shred tire if I stay this low. I'm thinking about changing the rear springs to '13 CJ Springs and running some QA1s in the rear to compensate. My question is, will they give me enough clearance or should I go with P-Springs? Questions, concerns, opinions, comments?

I run that size tire with Bmr springs and vmp. What is rubbing? Maybe it's the wheel offset?

 

[sleeper02]

yea, the offset is aggressive, and they are 9.5" which doesn't help.

 

[sleeper02]

the other option is to widen the rear wheels, or buy new wheels.

 

[blownby]

yeah need to widen wheel to sit inside better ...

I have same situation on 19" tho. 305/35 19 on 9.5 with 33ET

I am on eibach pro kit with out issues. Big gap and doesn't hit...
Want to go lower like you, but need to swap rims to wider

 

[evil281]

Do they offer that wheel in a wider size? I mean if you are spending 200 on springs why not just sell these wheels and buy the wider once so you can keep your stance if you like it?

 

[sleeper02]

unfortunately no, the widest is 9.5. To widen them I'm looking at $700. I picked the wheels because i wanted to be different. I believe the CJ springs drop 1.25" so i'm hoping ill get the clearance needed to launch while keeping some stance. I'm not one of those "hellaflush" ****, I just like the aggressive look.

 

[blownby]

well springs it is

 

[evil281]

Not sure how this wheel is constructed or how far off the offset needs to change to avoid rubbing but I know some wheels can can be shaved a bit on the face to pull them under the fender a hair more. I have never done this but my dad did on his camaro. Not sure how much can be shaved off.

 

[Rct851]

I had 7 mills shaved off the the inside of the some wheels. Zero vibration, worked perfect

 

[sleeper02]

I bought the 13' Cobrajet springs. Hopefully will be here within a week. Updates coming after Thursday.

 

[nosscort]

It's your offset.. regardless of springs it will still probably rub when you hit bumps or load the suspension launching

 

[sleeper02]

I plan to run a 15x10 with a 275/60/15 MT MT Drag Radial at the track. the NT555Rs are more for street operation with the occasional cruise to Mexico. They are more of a summer street tire. Hopefully the added clearance will minimize any rubbing. This is all until I pony up for wheel widening or new wheels.

I had the rear BMR sport springs swapped out for 13 CJ springs yesterday. Also the axle was realigned and centered. I was able to gain the clearance I need while maintaining the stance. Im very happy with the results. I should be making a pass next week. Ill let you all know how it works out.
