J&M Products Rear Suspension Results

[anthony05gt]

Yesterday I finally got around to installing my new J&M LCA's, adjustable upper, adjustable panhard bar and Steeda relocation brackets. My buddy has this same set up and Bigcat had recommended it to me more than a year ago.

My first impressions are how extremely quiet the J&M design is. Absolutely no additional NVH whatsoever. Their bushing design really is tops. The ass end of the car is very predictable now and solid. One major improvement is the fact that I can do a burnout with such control even with the tires barely spinning...no wheel hop or vibration at all.

I've got the pinion angle at -2 degrees, I welded the Steeda brackets in which it's a good idea to note that before welding in relocation brackets it's extremely important to ensure that your front to rear wheelbase is measured before any work begins and that measurement must be matched before you weld them up solid. It's very easy to screw this up causing one LCA to be set at a different angle than the other and your rear wheels will not track straight and in proportion to the front end of the car.

I highly recommend the J&M Products suspension offerings. Very pleased!

I agree. My BMR LCA's were quite noisy. The J&M ones are very quiet.

I try to tell people that all the time and nobody wants to listen. The BMR stuff has a bad habit of breaking bushings too.

another satisfied customer.

i cant say enough about the design of their parts, all are top notch for sure!

Believe me, I tell everyone that now. A broken bushing is what made me change to J&M. BMR offered to replace mine, but since they were loud from the get go and everyone was having problems, I went ahead and changed.

I just did L&M LCA's and I'm very happy. No noise, and now my wheel hop is gone as far as I can tell. As soon as my DR's get here its track time !

+1 for J&M. Quality stuff

it is good to know you have had success with the BMR parts. this thread was created to show that anthony was impressed with the J&M parts, not to start a flame war about which is better.

has anyone heard anything bad about J&M parts? i have not. my personal opinion is that i will not use or recommend any other manufacturer. J&M is top notch and service is awesome. i have even been given cell phone numbers of employees there, just in case there is ever an issue. that is service at its finest.

I love my instructions that I got with my J&M panhard bar, they look eerily familiar to instructions I saw on how to do it somewhere on here. Now only if I could remember where......

Lol yeah I was like...I just read this online.....

proud to help out J&M.

Congrats, Anthony
I can't hear/feel my J&M LCAs either

 

[anthony05gt]

Thanks. You know, all of the other rear suspension products I've used over the years always had me gaining a performance advantage, but the noise was always an issue. This was just a pleasant surprise to get the best of both worlds for once.

anthony, did you get an answer about the grease fittings from brian yet? he told me a while back that the supplied grease works so well, and the design holds it well that the fittings were not necessary.

I know this is a dumb question, but since i didn't see it in the instructions anywhere *cough, cough*, what exactly am I supposed to grease with the supplied grease?

these are technical terms here, so be ready


squirt the lube onto the bushing surfaces, except the outside edge, where it bolts up to the axle. spread it around to coat the entire surface. squirt some more into the LCA and rub it around again to coat the metal where the bushing will contact it. do the same to the metal sleeve, on the outside of it. dont waste the lube on the inside of the sleeve. assemble the bushing into the LCA. when you try to push it together, it will not stay put, the air and grease inside will want to push it out. assemble one side, then the other, trying your best to minimize trapped air. what i found when installing mine is that if you wait to install the grease fitting (if you have an early design) the hole will allow some air to escape, making it easier to assemble the bushing.

Crap, I guess that i should have mentioned that I was talking about the adjustable panhard bar, but I guess since my LCA's are on their way in, this info was pertinent as well.

 

[bigcat]

which adj. panhard did you get? the one with rod ends, or the poly ends? if you meant the poly bushings, just coat them the same as i mentioned above.
