how do DMS suspention products compare to BMR im already going to get DMS lowering springs but i want to know if DMS makes better LCAs and SFCs too

 

DMS = Granatelli

Personally, I won't run a poly/poly LCA anymore, but have had the Granatelli LCA's in the past. They are well made. I use and suggest the LG poly/rod end LCA's. Poly will bind, the rod end keeps everything moving freely as it should.

Chuck,
Please enlighten me as to how we are Granatelli? Huge difference there between both companies..sort of like saying Pepsi=Coke

If your getting lowering springs, you should probably get a set of matching shocks because the stock shocks would most likely be overwhelmed and not be able to dampen the springs effectively. And you'll probably want LCA brackets to make sure your LCA's stay parallel to the ground.. and you might want to double check your pinion angle..

 

Oops forgot to post my take on ends...

Poly bushings do not bind. I've always had poly bushings on my SS and have done it all (drag racing, canyon carving, autocrossing, etc) and never ran into problems. Naturally anything can fail as will a rod end. Poly
has deflection which makes it very streetable. Its better even then natural
rubber. IMO - having a poly bushing on one side and a rod end on the other
has no purpose. If you don't want deflection then why have poly on only one
side. Does that make it half right or half wrong?

Nice sales pitch. What you need to do is re-post this to the Auto-X forum. You'll get your answers there.

 

Personaly i think poly is good. They are alot stiffer than stock rubber and not as noisy as rod ends. The whole defflection thing is a concept that global west pushes for their spherical rod end's as compared to the poly's. If greased properly, poly should not be heavily affected by deflection. The only mismatch i thought to have a purpose is rubber/poly to soften the ride. Poly/rod end combos defeat the whole of perpose of haveing rod ends by the whole deflection concept. The only part i would seriously consider rod ends is on your a-arm's b/c they will have i considerable amount of movement compared to LCA's on the track. Anyways, If you are getting DMS springs than i would stick with DMS. Usualy suspenion components are engineered to match. They are all good and usualy price is the deciding factor.

Sales pitch? For those who know me here and seen my posts..I give my honest opinions as well as my experiences. I've never had any problems with poly bushings...however I do encourage him to ask around so that he can make an informed decision

I admit that I made an ***umption that you are reselling the GMS suspension parts based on your close physical proximity to Granatelli, the fact that you have offered GP's on Granatelli products that no one else to my knowledge even sells, and the fact that the photos on the respective websites show a very similar product.

http://www.granatellimotorsports.com/images/gm204.jpg

Note that they are flipped 180* in the photos. Your prices are MUCH better though, and as I stated, I have owned Granatelli LCA's in the past and they were a well made part.


I am sticking to my story that poly/poly LCA's bind up and need to be disassembled every 3-4 months to be greased. I have never had a set that would properly lube through the zerk. Rod ends are what most serious racers use.

 

I see where you are coming from. Keep in mind that in this industry, you form acquantainces, frienships, and conenctions with other manufacturers, vendors, sponsors etc. I have known JR for a while now and we've been good friends. You're right we're not entirely too far from one another (and equally close to Paxton, MMS, and Vortech among others). But that doesn't mean DMS = Vortech, or DMS = MMS etc.

Obviously many companies sell the same type products as all others (ex - we have our SFCs, Granatelli has their SFCs, SLP has their SFCs, BMR has their SFCs, and the list goes on). There is only so much deviation one can have between products. In many instances, companies have their products made from the same fabricator, however rebadged for thier company. Take LCAs for example, all LCAs look alike. Some are beter quality than others but they still look alike.

I'm not trying to change your mind on the poly/poly issue. Everyone has opinions based on experience. That's where I'm assuming you got yours. I have used poly/poly for years and never had any problems...guess I'm not now or ever was a serious racer then

No worries though..I assure you..I"m not Granatelli..you can ask the many that know me personally

Cheers

Look at all this free exposure - I love it

------------------
Manufactures of the only 50 State Legal "Truly Calibrated" Mass Airflow Sensors. Granatelli Motorsports Suspension components are back - Great parts and Great prices

 

I never meant to imply that DMS and Granatelli were the same company, and should have been more clear.

Also, Eric and/or JR might want to look at this post.

 

All is good buddy . Thanks for the heads up with that link...

That's the pitch. But as a salesman, I don't expect you to point out the drawbacks of your products. You're here to sell stuff (nothing personal, but it's true).

Of couse they do. That's why LG (and others, like GW) acknowledge this and offer LCAs with rod ends.

Yes, on a lowered car with higher rate springs, shocks, and sway bars there's not much wheel travel, reducing the occurrence of bind, but on an otherwise stock car they can act like a huge rear sway bar.

The bushing stiffness that makes them popular is the same thing that works against you when the arms need to rotate on their mounts - that's why grease does nothing for bind. But greasing them can temporarily reduce squeaking and stiction.

I tend to ignore this in the For sale and GP sections, but this is LS1 Tech.
