These are the best rear shock mounts that we have found for the E30, E36, E46, Z3 & E85 Z4! Featuring CNC-machined billet aluminum mounting base with a replaceable urethane bushing (replacement bushings are just $15 and are changed in minutes!). These mounts are excellent for either street or track because of their low NVH (noise, vibration, and harshness). Plus, the superior design will far outlast the life of stock mounts - maybe even the car itself. You'll never think twice about your shock mounts again! These shock mounts are a direct replacement of the stock mounts so they fit all shocks with the BMW-standard 10mm shock shaft, including all factory and OEM shocks (Boge, Sachs, etc), H&R coil overs, Bilstein shocks and PSS, PSS9, PSS10 coil overs (except the B16 Ride Control Kit). This is sold as a package with new shock mount gaskets, washers, and Nyloc nuts.

Swapping in E46 control arms into your E30 or E36 significantly increases negative camber by widening the track width and also gives you more clearance for more steering angle. Condor's CNC machined control arm brackets are made from solid steel and are fitted with a solid hex-shaped bushing. Designed for the street or the track, they hold the control arm steady and eliminate "shimmy" caused by stock bushings. They sharpen steering and improve overall driving feel. Comparable to the NLA Treehouse E36 & E30 Eyeball Arms.
Easiest install of any aftermarket solution
Allow clearance for E30 M50 Conversion exhaust
Street Approved, marginal increase in NVH
Easy Installation, no need for a press
CNC machined steel construction
Solid design without the maintenance of spherical bearings
Heavy-Duty replaceable UHMW insert. Don't be misinformed, UHMW is the best material for these inserts. Delrin is not self-lubricating and will crack and degrade over time.
Powder coated white for corrosion resistance
Improve caster with M3 offset geometry
Keep proper steering geometry under high loads
Made in the U.S.A.
Fitment:
E30 84-91 3 Series
E36 92-98 3 series & Z3
Note that you will need to use E36 outer tie rods and E90 inner tie rods when installing in an E30 or E36
Be sure to measure your control arms to determine if you need 21mm or 23mm. Meyle makes a standard e46 control arm and a Heavy Duty control arm. Most HD arms have a hex that is larger in size (23mm). Lifetime Warranty
ALTA Rear Control Arms are the ultimate upgrade for your MINI, replacing your rear lateral links with a solid and performance-focused design. These control arms enhance traction and handling while giving you precise control over camber and toe settings. The flexibility of ALTA control arms allows for fine-tuning without the hassle of removing and reinstalling the linkage. Simply adjust the lock nuts and twist the center section to achieve your desired settings.
These control arms are the perfect complement to other suspension products like springs, coilovers, or sway bars.
For a comprehensive rear end upgrade, consider purchasing two sets of control arms to replace both upper and lower control arms. This minimizes deflection from the OEM rubber bushings and reduces weight. Please note that on models with Xenon-style headlamps, some modifications to the leveling sensor mounting may be necessary. For additional details, consult your ALTA dealer or our Tech Department.
ALTA Rear Control Arms come with high-quality hardware, including corrosion-resistant spacers and Grade 8 adjustment nuts.
Swapping in E46 control arms into your E30 or E36 will significantly increase negative camber by widening the track width and will also give you more clearance for more steering angle. Condor's conversion bushings are machined from UHMW due to its high rigidity and low coefficient of friction allowing for minimal suspension bushing deflection (geometry change). They've designed them offset to re-center the wheel and give your e30/e36 the correct caster. They will include a stainless-steel insert that tightly presses over the hex pattern on the E46 control arms. You do not need to grind down your control arms or make any other modifications to your chassis. Please note that you will need to use E36 outer tie rods and E90 inner tie rods when installing in an E30 or E36.
