5-lug front adapter kit for BMW E30 with E36 / E46 front wheel hubs and E36 / E46 non-m or E46 M3 front brakes (not E30 M3 or ix)

This E30 5-lug adapter kit will unlock a huge selection of brake upgrades and 5×120 wheel options. MRT have paid extra attention to make the kits compatible with their roll-center and bump steer correction products to increase rotor to tie rod and LCA clearance. With E36 / E46 wheel offset (higher than on E30) you will keep the same scrub radius as stock and it will not affect front suspension geometry. Hub adapter is one piece part that will accept E36 / E46 hub (or wheel bearing), with a nut and a dust collar as is and does not require tapping or modifications on the E30 strut.

Main features of the front adapter kit:

• Accepts E36 / E46 front wheel hubs (BMW part no. 31226757024) and hardware as is
• Designed for E36 / E46 wheel offset (+17.5mm offset from e30 stock brake rotor flange)
• Dual bolt pattern, cnc machined aw-7075 aluminium front caliper adapters + spacers allow use of any E36 / E46 non-m or E46 M3 front brakes (not E36 M3 rotors) for example:
  286x22mm rotor + caliper from E36 318i – 328i or e46 316i – 323i
  300x22mm rotor + caliper from E46 316i – 328i
  325x25mm rotor + caliper from E46 325i – 330i
  325x28mm rotor + caliper from E46 m3
  325x28mm rotor from E46 M3 + caliper from E36 m3 or E34 540i – M5
  345x28mm rotor + caliper from E46 M3 csl
• Gives extra brake rotor clearance for the tie rod and lca end compared to competitors’ products, compatible with MRT Engineering roll-center / bump steer / angle-kits
  Abs option available

Grinding of the caliper carrier required for bolt head clearance with E36/E46 non-m brakes, combinations with 325mm or 345mm rotors caliper carriers or strut mounts only need a slight touch for sufficient clearance

Removing of the stock abs ring and pressing in a new one required with abs option

The kit can be used with E30 non-M struts, both 45mm and 51mm, ABS or without ABS. Not compatible with E30 M3 or E30 iX struts!
