The H&R Street Performance Coil Over kit takes the traditional shock/spring package one step further. H&R combines their progressive-rate springs with specially valved shocks and adds height adjusters that let you set the ride height to your own personal tastes. These coil overs are designed for street use with progressive rate springs that start out soft and stiffen as they are compressed. This helps to keep the ride compliant while still giving better handling and balance.

H&R designs each suspension to work as a coil over. This means that the correct amount of travel has been built into each shock. And the shocks are valved specifically for the spring rates to give a tight and controlled ride without being harsh or ultra-stiff. Each H&R coil over is TUV tested and approved and meets ISO quality standards. These are used with the stock strut and shock mounts for a quick and easy install.

Looking to stiffen up your rear shock mount without going for a solid rear mount? The Polyurethane Rear Performance Strut Mount from IRP will give you the stiffer reinforcement without giving you the typical noise, vibration, and harshness that come with traditional performance strut mounts. The polyurethane also helps with preventing rear shock blowouts, a common problem for stock BMW rear mounts that are paired with stiffer than stock suspension. 

The bearing sleeve and poly bushing are built to work with all stock style shocks such as Bilstein and H&R coilover and suspension kits.

Fits the following BMW chassis:
E36 BMW All Submodels except for 318ti

This aluminum spring seat fits between upper and lower 60mm springs to "join" them together. Typically you would have a main spring on top and a tender or helper spring on the bottom (or vice-versa). The spring joiner, or locator ring, fits between the springs with a retaining lip on the inside. We like this design better than an outside spring joiner because it's lighter and there's no material sitting on the outside where a tire might come in contact with it. These are priced per each.

Want the best performance option in shock tower mounts? IRP has created their pillow-ball rear shock mounts for just this need. These rear shock mounts are designed for use on the track and racing. This set of mounts will help your rear shocks perform the best they can in all conditions. The advantage to using a mount with spherical bearing is that it allows the shock to freely move off axis without side loading the shock shaft like rubber or polyurethane mounts do. Side loading a shock increases stiction and wear which decreases its efficiency. Because these are mounts without an isolator (rubber or polyurethane) to dampen road noise and vibrations we do not recommend them for street cars.

The bearing sleeve and poly bushing are built to work with all stock style shocks such as Bilstein and H&R coilover and suspension kits.

Fits the following BMW chassis:
E36 BMW All Submodels except for 318ti
E46 BMW All Submodels
