Hello, I was just wondering if anybody has any information on the H&R coilovers. I did a search and could find no information on spring rates, how well they work compared to other coilovers. Basically any information is gladly appreciated.

 

I don't know anything about their application on the RX-8. On an E46 M3 they're perfect, I didn't like them as well on an RSX. You could always call their US office and annoy them with questions.

 

yeah before the rx-8 I had a E36 M3 and everybody on the forums loved them, tirerack has a couple of sets for sale at a low price. The only concern is if you look through their reviews all of the nice cars that have them commented that they were too soft and were not good at all. On the other hand all of the people with civics and GTI's loved them.

I might just wait a little bit and go with a proven set up like KW2's, thanks for the response

 

Pay particular attention to the spring rates and especially the front to rear bias.

I have a set of H&R's on my Miata and the rear is overly stiff and in such, the car's natural balance is negatively affected. The Miata's natural bias about 2:1 (f:r) and the H&Rs are about 1.2:1.

Just like other makes, some cars work well with H&Rs and some don't. Research it well.

 

thanks for the response unfortunately H&R is very secretive on their spring rates for their coilovers and were completely unwilling to tell me anything about the coilovers all I could get from them was that they were a monotube design and that the rates were anywhere from 20-50% stiffer than stock. It just sucks because I would prefer to make an informed shopping decision on this and unfortunately they are just not going to win me as a consumer.

 

20-50% seems like a very mild increase considering other coilovers are at minimum bumping to a 400/280 rate from the 155/110 stock rate. I wonder if that's a true figure.

 

Not a good manufacturer if they won't reveal the rates.

Rcae teams won't use them.

 

That's just silly.

H&R supplies teams at the highest level of motorsport. Any serious race team is going to have a selection of springs. They aren't going to leave that to the company that built their dampers. And they are also going to have adjustable damping to get the last little bit out of the setup at whatever track they are running. The dampers in most H&R coilovers, a street product, are non-adjustable. They are built with parts supplied by Bilstein which, as we all know, is POS company that has never supplied parts or setup support for any successful race car.

H&R choosing not to reveal spring rates basically comes from a well-proven business strategy regarding protection of intellectual property, time management of its sales force, effective marketing commmunications, etc.
