sorry , my bad, was thinking for the rears

Rears are ti specific, a common upgrade is to buy M Coupe/Roadster trailing arms and brakes.

thanks , but not looking to upgrade, just renewing

Anyone have any experience with these? do you get what you pay for? or are they all pretty much the same? I'm looking to do an upgrade to m3 spindle/rotors, and I wanna do lines while I am at it. I already have 17" rims that will fit, and the m3 stuff came off my M3 may she rest in pieces.

I've been looking around and can't seem to find the answer to this question:
I want to switch from the stock '95 ti brake setup to the '95 m3 spindle hub/rotor, setup... will this change wheelbase/offset?
I know the stock offset of the wheels is 38mm vs 41mm on the ti vs m3 BUT I don't know if thats due to other factors or if its all in the spindle/hub making the difference, or if they just wanted the m3 to have a different wider stance without changing the hub design or something...

The reason I ask is because I will have to to put on different rims with the bigger brakes, I have the H&R coilovers, but the coilovers changed the geometry a little making the 17"x9" rims that I have not fit (by about 3-5mm, rubbing on the coil spring) if the slotted rotor/hub etc of the '95 m3 places the mounting point of the hub as little as 5-7mm outward I probably won't need to buy spacers and save some buck. otherwise I will need the Turner motorsport hub extenders and 7.5mm spacers. Anyone have any clue about the differences in the geometry?
The one thing I did find was that the '95m3 has a little more camber built into the spindle I think so that may change things a little too, and I am planning on replacing the control arms while I am at it, but am not sure if upgrading to the M3 arms will change things too... UGH... I know too many quesTIons but any help would be appreciated before I start ordering the wrong parts for the swap.

The difference in geometry comes from offset control arm bushings and strut bearings. The spindle has nothing to do with it. The reason you need bigger wheels is to clear the calipers since they sit further away from the hub due to the rotors being larger in diameter. Your 17x9" wheels probably rub on the coil for two reasons. 1, they're much wider than a stock wheel and 2, you probably need a lower offset(which may require you to roll your fenders).

All E36 non-M Models take the same line set.

I know the caliper is bigger, hence one of the reasons I got the bigger rims, to clear it. I also wanted to get a bit more traction with the m3 motor, the stock size steelies aren't doing it for me, thouhg I guess 17X9 is a little big... oh well I expected to have to roll the fender.

So what you are saying is there is no offset difference between a '95 e36 m3 and a '95 e36 318ti, despite it being a different spindle and rotor, from the chart going from a 286 x 12mm solid to a 315 x 28mm vented? the wheelbase for the two cars is identical? except I know the stock Wheel offsets which are 38 and 41 respecitvely if I remember correctly?

I know you may not know what BMW was thinking when they did it but... do they have different wheel offsets just to allow the m3 a wider stance and accomodate a larger wheel, but not have anything to do with where the hub actually is... like if I measured hub to hub in the front of an M3 and a 318ti it would be exactly the same distance (neglecting individual car to car differences because of manufacturing tolerances and worn parts)

The next question I have is...(and I apologize it prob doesn't belong in the brake thread, but it is related) must I have the m3 control arms to fit the spindle and also the offset control arm bushings? or can I just bolt on with the 318ti control arm centered bushing, because I don't want the extra camber right now from the m3 because lowering the car already changes the camber angle ...

I really have been trying to do my research but haven't come up with a difinitive answer yet. I will probbaly just order the TMS hub extender and 7.5mm spacer and call it a day... but I will still need to know about the control arms.
The help is greatly appreciated.

Its pretty common for a wide wheel to rub the coilover spring, most guys with M3s have that problem too. You can either use a spacer or get a shorter spring.

Stock ti offset is 46 for the 16x7 sport wheels, M3 is 41 f/r for the staggered DSIIs/Contours.

I run 17x8.5 et41 wheels on my car and they clear the coilover by only a few mm. I can easily see a 17x9 hitting the coilover if the offset is still 41.

Check out posts #80 and 96 in this thread for control arm differences.

I think an easier way to ask my question is... Is there a difference in m3 vs 318ti in the distance between the wheel well and the hub due to the different spindle and rotor depths? I will Check out the info for the CAs thanks for that.

No. The surface on the rotor that the wheel bolts to on both the M3 and the ti are exactly the same distance apart from left to right. Don't get confused by rotor thickness... it refers to the friction surface.

Also the larger diameter wheels are needed because of the rotors, not the calipers, but there are a few 16 inch wheels that will work on M3 brakes.

Thank you for the clarification. I got the same answer earlier today from a BMW dealer/shop/race garage so I ordered the TMS 7.5mm spacer and SS brake line kit. And I will go with the Meyle HD lower control arms for the 318ti(non m3 e36) with a solid bushing to tighten it all up. Without adding caster and we'll see if it makes more sense to go with the centered or offset bushings to adjust the camber back closer to 0 or keep some negative etc...Hopefully it will all fit and I will have the shop roll the fenders too. I'll let you know if I run into any more problems to help anyone out there trying to do the same thing with the bigger 17 x 9 rims w/ stock m3 41mm offset (I think they are 41 anyway) m3 brakes etc... Thanks for all the help and useful links.

FWIW, My style 5's rubbed on my M3 calipers. The calipers straddle the rotors, so they'd hit the wheel long before the rotor could.

Confused
 

So I have been reading this thread in an attempt to get a handle on what my options are for upgrading the front brakes on my 99 ti.

If I understand what is outlined in the thread, if I were to use a rotor that is over 300mm, I would have to increase my wheel size from 16 to 17 inches.

But Turner Motorsports offers a Brembo Big Brake kit with 320mm rotors that shows it works with 16 inch wheels http://goo.gl/nIYgO (lines 2 & 3)

What am I missing?

By using 300mm rotors (E46 328) and the corresponding caliper carriers you can upgrade run the 300mm brakes. They only require 16inch wheels.

You cannot go by just rotor size to determine what size wheels you can use. The caliper will be the determining factor as the caliper sticks out further than the rotor will.
