[g57yle]

i am nearly there with the fronts.

now for the rears

apparently the rear of the Z3 is different to the 318ti

i would like my rears to be as in as possible

does anybody know the difference between the z3 width between the wheels and the 318ti width.

my car has standard wheel arches

ThanksThanks in advance

there are 3 options for the rear axle:

1. instal the 2 swingarms from a 325i E30, and replace the 4-bolt flanges with 5-bolt flanges from the E36 323ti compact, it fits. take the brake disc from a E36 323ti compact and machine the outside diameter of the disc smaller to the size of a 325i E30 brake disc. then you have 5-bolt with the same brake as a E30 325i

2. instal the 2 complete swingarms and driveshafts from an E36 323ti compact or Z3. it fits the E30 perfect. then you have 5-bolt with bigger brakes than the E30 325i.

3. install the complete rear axle from the Z3 M-coupe. then you have the biggest rear brakes that bmw makes.

option 3 is very expensive because there are almost no used Z3 M-coupe parts for sale.
option 2 will cost about 400 to 550 euros.
option 1 will cost about 300 euros.

i think option 1 is the easiest for you, because E30 325i swingarms are easily available everywhere, and the 5-bolt flanges and the brake discs are for sale at every BMW dealer

For the front, I have such a recommendation, though 17" wheels are minimum then...

front shocks take E36 M3 3.2 GT
topmounts for the front shocks take E36 325i
front swingarms take E36 M3 3.2 GT
front swingarmbushings take E30 M3 Group N excentric
front hubs, brake calipers and brake discs take E36 M3 3.2 GT

size of the brake discs is 315mm x 28mm, these discs have a centre made out of aluminum.

quite costly, but best performance also for this money...
