CB005 + Steeda Diff Inserts

[BMR Tech]

Very minimal.

FWIW - I have Delrin bushings on my car.

I have shimmed the cradle as much as .562" and have seen just about no ride height changes.

Thanks for your insight, bud. :cheers:

NP.

I wish it were true though.

We could just make an adjustable height cradle bushing kit and market it as a "coilover Kit" - hahaha

Funny because I was just about to chime in how my car looks "higher" too. I think my car is not necessarily sitting higher, but has a little bit more gap between the tires and the well because I put on some new wheels along with this upgrade. Turns out the wheels/tires are much wider, but slightly smaller in diameter from stock.

Question for the BMR guys; I know I have read in another post that the combo of bushing inserts and cradle lockout adds some potential noise, but I have not heard of any reports of vibration. This car rattles/vibrates quite a bit now at speed. Now, I did get new wheels/tires, and unless they happened to fail at balancing them after mounting to the rims, I feel like there is some other underlying issue. Unless of course the vibration is natural with the inserts/lockout kit. Everything is definitely "tighter" down there so I'm figuring that an increase in NVH is normal; I kinda feel that vibration isn't really related to the cradle/differential and how its connected however. Just trying to make sure I didn't screw anything up with the install

New rims and tires and now you have vibration?

In no particular order:

1) Improperly balanced wheels
2) If you need hub rings, wrong size or cracked or lack thereof
3) Off-center IRS coupled with locked out bushings
4) Bad tires
5) Forgot to torque down something
6) Call BMR and talk to them because it'll be faster.

The BMR CB005 raises your ride height because of the way the subframe lockouts are designed. You dont get this with some of the other systems out on the market.

um? because you saw pics on the internet and assume it does? negative homie. zero lift.

The Steeda Subframe brace will be here mañana. I will take before and after measurements. I am taking the BMR Cradle Lockout Kit off. Could be a handful of us that have installed it incorrectly but maybe not. It is a pretty straight forward install. For the little bit that it raised my GT it still is worth the price. Did a great job helping to control wheel hop. Still have wheel but much improved. Also will be installing rear diff. bushings and subframe alignment kit this weekend.

Update:

I finally got decent rear tires this morning and drove around on the streets for a good while testing the car out. I also have upgraded halfshafts and would say the halfshafts only lightly dampened the wheelhop I used to have post the CB005 and Steeda inserts mod.

I could not get my car to wheel hop on the 1st to 2nd shift today. Before my rear tire upgrade, the car would always hop moderately on the 1-2 shift. I still rolled into 1st gear so I'm not reporting on the aspect of launching just yet.

It feels great to finally have complete traction to far better enjoy the car. I was driving and couldn't believe the car was hooking and that the car wasn't hopping around. What a great feeling to give wheel hop the middle finger.

I never cared to add more power until I could have the car hook with the power it already had.
Once I get my Konis, I'm sure it'll be even more fun.

In summary, if you want to kill wheel hop and have traction, the CB005 and Steeda inserts is a step in the right way.

Sweet. Thanks for update.

I am no mechanic so I have somebody that does my suspension work. No crunching with steeda black and cb005 combo. I did pick up gear whine that is very minor.

Thinking about it again, my crunching sounds might be because I didn't use any of the provided lube for the inserts.

Can you explain in more detail what you did to get this bolt in here?

 

[ForTehNguyen]

you have to remove the front subframe bolts to sag the front to put that bolt in. CB005 requires you to do this anyways so you slip the diff inserts at teh same time

 

[joleobee]

I removed the front subframe bolts, I didn't remove my aftermarket exhaust though and I'm hoping next time I give it a go the subframe will drop a little lower when i do. If not i'll try to pry the gas tank half an inch forward I guess to place the bolt.

If you can't carefully bang the bolt in with the rear subframe bolts tight and the front subframe bolts loose, you will need to get the rear subframe bolts loose as well and really droop the whole subframe to have enough clearance. Upon doing this, you will need an alignment, however.
