PSS9's on my M3 and they were great but i hardly ever adjusted the ride height or damping.

I would recommend TechART springs if you are worried about trying to keep the Factory feel.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

I will be purchasing H&R Sport springs soon and i just wanted to know if anyone has had any negative or adverse effects with their springs? Do the stock shocks hold up to the stiffer spring rates of H& R springs ? I think that with some instances (usually Japanese imports) that when you swap ONLY the springs that you get a bouncing affect that only coilovers will remedy. Does the bouncing affect happen with only a spring swap on our Cayman(S)? I had Bilstein PSS9's on my M3 and they were great but i hardly ever adjusted the ride height or damping. I really don't want to pay that much for suspension, but if there will be problems with the stock shocks holding up, i'm willing to splurge. T.I.A.:cheers:

POST 2Original post

Have you looked in the Cayman modifications forum. There are some H&R threads if you have not already read them.

POST 3Original post

I dont think you will have any issues. I put the H&Rs on my CS (with PASM )and the springs are really only slightly stiffer. No adverse effects.

POST 4Original post

I would recommend TechART springs if you are worried about trying to keep the Factory feel. They are the only springs that drop the car one inch. Eibach would be my next choice, they drop it approx. 1.2 inches.

POST 5Original post

porsches4ed: i thought the Techart and the Eibach springs are the same? i've read from somewhere that Techart uses Eibach springs . you only talk about the height drop in both eibach and techart springs. how about H&R? anyone knows about it?

POST 6Original post

techart's spring is made by eibach with eibach : you could see that the gap between the tires to the body is slightly higher on the rear but with H&R the front side gap will be higher than the rear. so.. its your call.. slightly stiffer but drive good.

POST 7Original post

Eibach makes the springs for Techart. We carry the Champion Motorsport Springs which are made by H&R. We actually have a special on these springs now here is the link: http://www.planet-9.com/showthread.php?t=10081 H&R springs lower the front by 1.4" and the rears by 1.2 inches.

POST 8Original post

I'm confused Are the Eibach 's sold by techART the same as the Eibach 's sold by Eibach ? and are they both 1" drop or 1.2" or 1.4"? If I bought springs for a Cayman I would want to keep the drop as small as possible I think, just a tiny bit, maybe 3/4" to 1"

POST 9Original post

I've had H&R's on my (non PASM ) CS since the day I picked up the car. 17,000kms and about 20 track days later, no incompatibility issues at all, and I am very pleased with the mod. Stiffer ride, but not problematic. The only issue was the rate at which the springs settled. It took 3 alignments over 4 months before I got the set-up right. Not a big deal.

POST 10Original post

I had the same concerns but my Eibachs are great. Ride on normal roads isn't noticably different. Eibachs lower the car 30mm - so it's now the same height as GT3 I believe. I do scape the front often on speedhumps etc. but its no big deal. splitters can be replaced and none of the scrapes are visible unless you are under the car. On the track the car definately handles better. Feels much stiffer and more stable in fast corners, but that might be because of more track time since I had the car lowered. I also had a full track alignment when springs were put in, so much of the improvement may have come from that? My lap times have come down considerably and the car feels better - so only positive effects from the springs.

POST 12Original post

I had the dealership lower the car with the H&R kit before I took delivery, so I can't compare/contrast to the factory settings. With more than 7,000 miles on the car and many track days - I'm very satisfied. It's low and you have to be VERY careful with the nose. ...actually it's not the nose that hits, its an air diffuser that hangs about 2" lower than the front bumper cover. The ride is firm, but not harsh and the finished look is awesome. gratuitous photo link
