Subject: Re: E30 5 stud e36 brake conversion ???? (124 views)

Message: 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 325i2. 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

what is the "swingarms"?
is it so simple?
comments?

"Swingarms" are the rear trailing arms. It is that simple at the rear. You can use M3 E30 trailing arms as well of course.

thank you, what you suggest for the front? nikos

The rest of the E30 M3 suspension, although I've seen posts lately about fitting E36 struts. Don't know if the suspension geometry remains as good though.

thank you, so the conclusion is, ether you find the m3 suspension or you keep yours and you go for a big brake kit.

Hello. I am just wondering about doing the 5-lug conversion. I have a E30 318is, it has the same rear trailing arms as the 325i. So I need just the 5 bolt flange. Is that part in the picture below with the number 1 ? The bearings remain the same? Thank you.
