What about standard shocks with Eibach springs?
The b12 kit is basically standard shocks with eibach springs , except the shocks are made by bilstien
The B12 kit does lower the car somewhat:
E36 M3 Kit: http://www.bilstein-shop.com/bilstein-bmw-series-e36-b12-pro-kit-p-9459.html
But the ride is what you'd expect from stock M3 suspension, firm but not hard.
Bilstein B12 kit would be best for the road. Coilovers would be a waste even if you did find the comfortable set because once you set them its very likely you wont touch them again.
BUT, what you want to remember is the B12 kit offered for the E36 M3 is not really a proper B12. It is B6 dampers which are meant for OEM SE length springs. You want the B8 dampers which for some bizarre reason Bilstein don't do. There is a way around it though. The Z3M is the same as a E36 M3 suspension wise one the front only. So what you want to do is get the B8 for Z3m for front and B8 for e36 on rear (E36 dampers are all the same on the rear so you can get B8 for any E36 model except the Compact). Then get either Eibach or H&R springs to go with the B8 dampers.
Best combo because for lowering springs you want a shortened damper not OEM length one as shorter damper takes into account the shorter spring and works in full harmony with it.
If you want OEM M3 height you can use the OEM M sport M3 spring with the B8 damper as Bilstein list the B8 for lowering springs and OEM M sport springs as they are 15-25 or so mm lower than SE. Personally I would go with a quality aftermarket lowering spring. Just don't slam it. H&S list the drop as 40mm front but its not, its 40mm for SE so on M3 it will be about 25 or so. Its a little lower than Eibach on front and a little higher than eibach on the rear. Gives a lovely rake stance and H&R are stiffer than Eibach.
I think I have H&R rear springs in the garage somewhere so if you can get yourself just the front ones you can have these cheap off me.
H&R coilovers worked really well for me on my last Evo. I didn't slam the car so maybe that's why but they were brilliant on the crappy roads around mine.
Ive also had the Koni adjustables with H&R. Another awesome setup for the road but there is a lot of pi$$ing about with the fronts as they are inserts so you have to cut open the OEM shocks and insert the front koni's into that.
Also the rear are a stupid design for adjustment because you have to remove them from the car to adjust! They are best set to medium. you'll need a vice or something to hold them in then push in and twist. Or some cr4p like that.
B8 fronts for the E36 M3 are:
Left - 35-105855
Right - 35-105862
I have them.
That's a B6 not B8
The B8 is part number 35-044048
Here is pic of it. https://www.ebay.co.uk/itm/Bilstein-B8-Front-Left-Strut-35-044048/142729748484?fits=Car+Make%3ABMW%7CCars+Type%3AM+3.2&epid=1738064845&hash=item213b5b2004:g:Sx8AAOSwdu9aslw4
Is that a rh or lh shock absorber?
It says left on advert
I can't read!!
recently did Eibach (not the stupidly low ones) and OEM sachs dampers all round.
If you find my post you`ll see i also fitted larger rear spring pads as the rear was too far from the stock height.
Those part numbers are interesting, I simply pulled my from the link below for the purposes of this thread and didn't cross-check them.
They also list different part numbers for the B6 here as well.
Either way, I have B8's on mine and didn't have any trouble ordering them for an E36 M3.
Hmm that is strange. The B8's come with blue piston cover from what I can remember. Are yours blue or black?
Don't get me wrong, I'm not suggesting BW is correct, just pointing out my source.
I actually think I'm using the OEM bump stop and tube on my fronts, I'll have to make a point of checking.
you shouldn't have oem bump stop for sure on front. front B6 & B8 have their own internal bumpstop at the bottom, inside the shock body as they are upside down monotubes. They just have a cover to protect the shaft from road grit etc
I agree. Whilst not claiming that OE is always the best, most people compare knackered springs/dampers with brand new aftermarket kit and then claim how much better they are than OE. Not necessarilly the case, try comparing new OE to aftermarket and the results might surprise. Don't forget how much BMW spend developing the suspension on cars like these. AND, this is before we've even got onto the knackered bushes etc!
If you go OEM SACHS with Eibach mach sure you get the thickest rear spring plates if you don`t want the back end too low. Mine was fine up front but too low at the rear. If you search my other threads you should find the details.
The height is spot on now
