Hey all I'm building a front suspension, I was planing on using my stock '95 318ti top hats, until I saw a killer deal on a set of 96+ m3 offset strut mounts. I have bilstein sports and h&r race springs and offset control arm bushings. I read some info on installing the m3 mounts "swapped", but never found if also having offset control arm bushings would cause issues. | | | 10-04-2017, 01:45 AM | #2 | Senior Member Join Date: Dec 2011 Location: SoCal Posts: 702 | Quote: Originally Posted by NoobsaurusRect Hey all I'm building a front suspension, I was planing on using my stock '95 318ti top hats, until I saw a killer deal on a set of 96+ m3 offset strut mounts.

It can also give you more caster, but only because you are moving the top of the strut back, and not because you are moving the wheels forward. I guess it depends on what your trying to do. __________________ ***328ti Build thread. *** Even more important: SUPPORT 318ti.org! CLICK THE LINK ABOVE!

Just make sure you have a alignment. I'm not making any claims on how "optimal" it is, just that it will still be functional. __________________ ***328ti Build thread. *** Even more important: SUPPORT 318ti.org! CLICK THE LINK ABOVE!

The 95 M3 LCA and the offset LCA bushing and the proper upper strut bearing. keep in mind the steering knuckle is different as well. Having a donor car is the easiest method. I just purchased new LCA's from eEuroparts oem for 135 each, adding my e46 ZHP rack at the same time should be enough for now. | | | 10-04-2017, 10:38 PM | #5 | Junior Member Join Date: Oct 2017 Location: AZ Posts: 4 | Quote: Originally Posted by E30-M3 ... 95 M3 LCA and the offset LCA bushing and the proper upper strut... | Are the m3 LCAs offset themselves?? I thought I heard they were the same as non m ones but they're lighter. Right now I'm using stock 318ti LCAs w hd ball joints. I figured having offset bushings (actually I have offset solid "treehouse" mounts) and offset strut mounts would give me a wider stance with better handling. I'm on bilstein sports and h&r race springs, 18x7 z3 wheels with 225s. The goal is to swap in a m50, do some chassis stiffening, brake upgrades, and an exhaust so I'd like to get a little more grip outta the front end to keep me safe. | | | 10-04-2017, 10:46 PM | #6 | Junior Member Join Date: Oct 2017 Location: AZ Posts: 4 | Quote: Originally Posted by anassa ...

When the stock parts fail I lIke to get aftermarket stuff when it provides a benefit. | | | 10-04-2017, 11:54 PM | #7 | Member Join Date: Aug 2017 Location: MA Posts: 65 | If you start mixing an matching you might end up with something that's not streetable. | | | 10-06-2017, 03:16 PM | #8 | Member Join Date: Nov 2015 Location: missouri Posts: 99 | The lower perch on the strut of an M3 is smaller than the ti. If you put TI struts on an M3 mount the strut will hit the inside of the strut tower on turns. I've already done this. So i use all m3 parts and then cut the springs down to get the ride height i wanted | | | 10-09-2017, 03:15 AM | #9 | Senior Member Join Date: Dec 2011 Location: SoCal Posts: 702 | Quote: Originally Posted by andakn The lower perch on the strut of an M3 is smaller than the ti.

The lower perch for the spring is smaller on the m3, but the m3 strut mount I think will fit fine on non-M strut? I haven't tried, not sure Preferable to not cut the spring! __________________ ***328ti Build thread. *** Even more important: SUPPORT 318ti.org! CLICK THE LINK ABOVE!

On non m3 struts it is wider to fit the wider springs and its also flared out. When you add the m3 offset mounts the flared part of the strut will hit on the inside rear of the strut tower. | | | 10-09-2017, 04:02 AM | #11 | Senior Member Join Date: Dec 2011 Location: SoCal Posts: 702 | Quote: Originally Posted by andakn The perch is the cup of the strut that the spring sits in.
