Strut Bars/Sway Bars

I feel like putting a strut bar and probably sway bars if i finally opt to get the car. My questions are:

1. Does the OEM performance front Strut bar made for E92 335's fit the M3?

2. Is there rear strut bar for E92?

3. What are the specs of stock Sway bars? did anyone take them out for aftermarket ones? I am also wondering if the subframe needs dropping in the process of installing the rear sway bar.

It might be too early for those questions, but im hoping some people in Europe have played with the car or heard... etc.

Are they needed? The E9X chassis is a fine chassis, rigid as hell. The front already has a strut bar of sorts anyway - not sure if a traditional strut bar will help much

on my 335 sway bars made day and night difference. it was soooo flat it was ridiculous!

as for strut, i heard it makes a huge difference. strut is easy and i'd do it. but if sway bars is as PITA as 335 then im not gonna do it

yah i saw those. but you can put a bar across from one side to the other, on top of these. I'm just wondering if the OEM CF bar can be fitted with the V8 engine/hood/vents.

I doubt many (if any) suspension parts for the 335i will fit the M3. Totally different suspension, of course close but truly totally different. The strut towers are in the same location but clearing the engine is the consideration with regards to a strut brace. Read the after sales training pdf posted here on the forum that shows all of the suspension differences

Mantis, I bought my rear strut bar from ACS and is on its way now.

Maybe I'm missing something here... but I seem to remember that huge hood bulge... that functional hood bulge...

And then that Airbox that sits promptly right on top of the engine, filling up that familiar hood bulge. I don't really see how there would be any room for a strut to be placed over that. It would have to bend upwards and I think the angle needed would provide room for deflection of the bar itself.

Not to mention it would look awkward.

look awkward?! least of my concerns.

well that's why BMW performance has some homework to do to fit that thing in there. im sure they will produce something. but from what i remember from engine bay i think they can fit something in there behind the air intake

There is no way your going to be able to fit a strut bar between the towers anywhere, there is simply is no clearance all the way back to the firewall, the hood bulge is there for a reason. Next question is why? the e92 as said above is already an exceptionally stiff chassis and the m3 already has a very large 'dome strut' as shown above which connects the struts to the firewall. So even if you could fit one, a strut from one tower to the other would provide negligible benefits at best on this car IMO. Also where the rear strut towers are is already a very stiff and reinforced point of the chassis again imo you wont feel much/any difference, your much better of spending the money on something else.
