Will m3 evo sway bars / anti roll bars fit? The front one is a different shape but same mounting points and the rear is 22mm and has more curves etc. Thinking with the rear for sure will be significant upgrade from 14mm?

E30 M3 Evo's were 14.5mm if I remember correctly. They changed the spring rates and the shock rates for the Evo's.

BMW E36 M3 3.2 evo rear anti roll bar is 22mm?

M-technik-3 08-26-2013 12:45 AM

Might be, That I have no idea on, but Traditional e36 have different suspension than Compacts and Z3's.

What a difference the m3 sway bar makes to the rear would recommend the work. Needed to move arb brackets over by the width of the bracket each side and weld up then the bar bolted straight up, much tighter back end feel now.

I'm a little late to the party on this but H&R makes a 21mm rear bar and Dinan has a 22mm rear bar... both adjustable. No mount modification required. That would have been an easier way to go but congrats on your innovation.

Got bargain price on m3 e36 front and rear bars so worth the saving

- The 1995 m3 bushings are offset and solid.
- The 1996+ m3 bushing are solid but not offset.
- Tree House Racing: Offset, urethane, Pre-Pressed(Big Plus for DiY types)
- Ground Control LCA bushing, Offset, Delrin encased in metal,
- Ireland Eng, offset, urethane

Ireland Engineering carries Delrin centered and offset bushings, they do not have urethane bushings currently. I carry centered urethane bushings and 100% solid rubber lower control arm bushings (M3 bushings are not totally solid) when I can get them in stock. I sell the urethane, delrin, and every stock bushing pre-pressed into new backets for easy install.

- See above for the Meyle control arm/ball joint combo.
- e30 m3 aluminum control arms work too, but recommended replacement is every 2 years or X track days.

E36 M3 arms will also work and have better ball joints.

I do not suggest bolting the sway bar to the E30 M3 aluminum arms as they were not designed for that. E30 M3 arms should be used in conjunction with strut mounted sway bar links.

Ireland also makes 2 different camber kits for the E36. There are also several fixed camber plate solutions from Turner, Dinan, and using the OEM 96-99 E36 M3 mounts (spring clearance may be an issue with the M3 mounts).

- 318ti stock sways (non-sport) 25mm front, 14mm rear
- HR
- Turner MotorSports
- BMW OE Club Sport (26mm front, 16mm rear)
- Racing Dynamics
- Europe Only Eibach(need this confirmed)
- AC Schnitzer(used to, not sure if it still made)
- eibach

Club Sport bars are the same as Sport Package bars.

Dinan also makes bars. 27mm front and 22mm rear.

Z3 M Coupe rear bar is a great upgrade for a non-coil over car. 19mm

- Ground control (urethane)

- TcKline- Buna rubber or solid spherical for race applications

Ireland makes billet/urethane rear shock mounts that work great and they come with reinforcement plates. You can also upgrade to factory E46 M3 rear shock mounts with factory reinforcement plates from the Z3.

I believe Turner carries delrin mounts. Ireland also has urethane mounts. For mixed street/track use I prefer OE solid rubber or OE MZ3 mounts. They transfer MUCH less noise and stress.

Did you install the front bar as well?

Johnomoby 08-26-2013 11:06 PM

Yes fitted and feels good, the bar is deeper than orig but seems to work well

Did you change the sway bar mounting points or do you have the M3 bar hooked up to the control arm?

Johnomoby 08-26-2013 11:15 PM

Sway bar fitted to existing mounts with fresh bushes and connected to control arm with orig drop links, which I plan to replace now that know all works with coilovers and lowered etc

You actually downgraded the front bar. The stock bar is thicker than the M3 bar and will be more effective than the M3 bar when the same mounting points are utilized.

Johnomoby 08-26-2013 11:35 PM

Would existing bar still fit around sump tho if converted to a 6pot longer 328i engine?
