Im Stuck!! BMR Sub-Frame Connectors or Hotchkis Brace

Im torn between the two!!!

I like Hotchkis, but when it comes to Sub-Frame connectors it just seems like BMR's type connects better.

Please give your opinions.....

Vendors, please explain why your product (what type of material...ect) is better and why it will stabilize everything better.

Any advise would be much appreciated.

Does anyone have pics of either one installed and can give their 2cents?

I (and everyone else in the industry) get asked, "What is the best ______?" all the time. All products have advantages and disadvantages over their rivals. The Hotchkis has feature I like over the BMR, and the BMR has features I like over the Hotchkis. They are both great products. In the end both of them are WAY better than stock and unless your last name is Hubinette or Schumacher you probably will never get close to driving your vehicle in a manner in which the limits of any suspension product will come into play.

In a nut shell, either one would be a great choice that I think you will be happy with.

Neither. I got the Pfadt solid subframe bushings. Far lighter and more effective than a brace. Getting them installed next week with rear toe links. Already put in KW V3 coilovers, Pfadt f&r sway bars, end links and rear trailing arms. Corners flat and on rails. Loving it. Can't wait to get the solid bushings in.

Ive already bought Pfadt Sway Bars, Pfadt Trailing Arms and Pedders Coilovers. They are not installed yet, but i know once they are, i will be very pleased with the results.

I saw the Pfadt Solid subframe bushings, but i guess i need to do some more research on them. To me it doesn't tie the whole system together very well, but i just glanced over them. Going to look into them now. Thanks

I installed my BMR connectors yesterday, along with rear trailing arms, toe links and driveshaft tunnel brace. You are right, bws_82. The BMR parts connect just fine. In fact, I had planned to have someone help me at least hold the connectors while I got all the bolts in but I was able to do it by myself. All the hardware comes with and it is all bolt on. In fact, I ordered all my parts at once from Speed Inc. in Schaumburg Il. and got a little better price with free shipping direct from BMR.

Here is a good video and explanation of the Hotchkis brace and why I went with it. Pay particular attention to the subframe bushings and the part about what really moves and what doesn't. Also there is mention of the bushings being allowed to move some which allows for better NVH levels...

it's near the bottom of the thread...

So much to do Trailing arms going in next week. KW V3s in, but need spacers for the front wheels since they don't clear the springs.

Haven't had a chance to put her through some paces yet; still waiting to get her back from Stillen ;(

Bushings next - if I can figure where to start.

For the Hotchkis install, yes - just up on ramps

Like this:

Ok, not like that - actually the other way around!

I apologize for taking so long to reply. We just returned from Camaro 5 Fest. What a blast!!

The BMR subframe connector connects the front subframe to the driveshaft tunnel to the rear subframe.

The best way to stiffen the chassis is to connect the subframe connector from one solid point (front subframe) to another solid point (rear subframe). Even better if you can connect to a 3rd solid point (driveshaft tunnel).

The best way to stiffen the rear cradle is to replace all 4 of the stock rubber bushings with 4 stiffer polyurethane bushings. The BMR sub-frame connector does not attach to the rear cradle because this will not significantly dampen the 2 back rubber bushings.

By the way, the BMR piece is $150-$200 less expensive as well.

BMR will be releasing our polyurethane Rear Cradle Bushings in 2-3 weeks.

Thanks again for the Responses!! Sure is helping.

BMR your system is cheaper, but to connect to all 3 points wont i also have to buy your tunnel brace?

Yes, the tunnel brace does make the final connection between the two connectors...AND our system is "less expensive", not "cheaper"

I'm interested in learning more about the bushings. I have been planning on doing SFCs but some newer developments have come up where I am starting to question the need. It seems like almost everyone says the chassis is super-stiff, and it's quite obvious those cradle bushings are really soft, so I know, for sure, those are going bye-bye. As much as the ones that I'm looking at are, I'm really reconsidering SFCs. It'd be nice to find qualitive data that will actually so the benefit of the SFCs, even after replacing the bushings. To me, I just don't know if the money it would cost to replace BOTH is going to be there and even if, whether-or-not it's going to really be worth it to do both. I'm sure for a car that's going to a track a lot, SFCs are going to help, for a street car, that might see some Test-and-Tune action, or just some fun hot laps, maybe it's not totally necessary. I'll tell you that I've seen some FAST 4th Gens, that didn't have SFCs, that really twisted so I'm not taking ANYTHING away from either of these companies (please don't misunderstand). I have used products from BOTH companies and will likely go back, but seeing is believing

Respectfully...
