none apart from front ones

rear springs bottoming out,noisy,cutting grooves in my tyres

save a bit more money and buy quality,still trying to get refund even if they do advertise 5 year guarantee,fobbing me off with sending springs to Germany for testing.

Extreme track car-like cornering and stick.. Rocksolid and stable, even at extreme loads

Way to stiff/hard for everyday comfort driving and use.. Makes rough roads painfull to drive on!

I have driven several bmw 3 series with and without these springs installed, and really, when it comes to active/agressive driving and track driving these springs really gets the job done.. The car really does corner extremly well and has great road contact.. However, if comfort is what you value the highest, dont get these springs.. as they are rock solid, litterally! As I do a lot of track/competition driving, given my experience with this product, I would not have any toughts about recomending these springs for track use. For everyday road use however, I would not. Especially not if the road standard you drive on regularly is rough/bad!

Improved body roll and lowered center of gravity. Great appearance and performance. Came with front & rear urethane bump-stops.

Sudden give when cornering near the limit. Rear end frequently hits the bump-stop. As with any lowered car, scrapes on speed bumps and some drivways. Very rough ride.

These were the single rate springs. They dropped my car 2" on all 4 corners. They are 750Lbs. front and 350Lbs Rear. I really like the lowered stance and they handle great. Anit-squat is great in hard breaking and in average cornering, they hold the car level. In really hard cornering, they do give way pretty suddenly though. The ride is also pretty rough. H&R's gave better ride quality and dipped evenly in varying degrees of cornering.

for USA lads: you better try cars like mine, your oversised sh*t cars ride like cargo vessels.

sh*t springs. hard and not progressive at all. they even damaged my BILSTEINs. replaced them with VIDEN springs: as cheap as crapJAMEX but the ride is 100% better so is handling and cornering. could also recomend APEX and EIBACH my mates used on their 16v SAXOs and kick a**

car looks good

no suspension travel, you hit a hole and as if you didn''t have any shocks or springs, you could really feel a harsh ride ( I had 17"wheels with 215 45 Toyo''s on

the looked great, it must have lowered 3 to 3 1/2 inches

THESE SUCKED!! dont every buy these

The weakness is that they blew my shock in less then .0 of a second. before i even got the rim on. They blew!!

These just plain old sucked monkey balls. Cheap springs mean cheap everything. Im getting a set of Eibach pro kit. they are WAY BETTER! PLEASE GET EIBACH!

eibach pro kit is a fùcking god compared to this company/spring

Lower ride hieght by 2 inches, Hot looks, Great Handling, Almost zero body roll.

Really low sometimes it will drag on driveways. Ride is not as smooth as before, can be harsh under rough road conditions. Needs a stiffer shock to improve ride performance. Some wheels may not fit any longer with the drop in height, you really have to watch the offset of your after market rims.

Definately a blast to drive on. I love the new lower look. The stiffer ride doesn't bother me, but I have had comments from passengers that it is rough. Also I have noticed my passengers do not like the speed at which I can negotiate curves. Thay seem nervous until they find out just how well this thing handles with these springs.

Very stable and strong. Performance of car is noticable...which in this case is very good!!

The variety of the drops. Should have more options.

Paid $150Cdn for a used set of 4. So far a wonderful buy and I've had no problems with it. The ride doesnt suffer and the cornering is noticable. The ride is still soft and smooth but aggressive during hard cornering (depends on the drop). I would highly recommend this product to anyone who is just starting to trick their cars. For advanced lowering I would suggest buying a set with shocks (the standard shocks will get worn out).
