Hey everybody, I was thinking about getting 4 rotors and calipers off a 325is. Do you guys know if it's a bolt on upgrade, or do i need to modify a few things? I know that 2ndBimmer has a 325i brake upgrade on his car. Is there a difference between 325i and 325is brakes? I assume that there isn't any, but just wanna make sure. Finally, do you guys think that the rear brakes will fit onto our cars? Thanks guys -Randy __________________ 97 Jet Black 318ti Sport. Not so stock anymore!....

The rears won't fit. There is no difference between 325i/s or 328 i/s. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 04-11-2005, 12:43 AM | #3 | Senior Member Join Date: Aug 2004 Location: Tyler, TX Posts: 1,022 | I believe the E46 32X rear rotor/caliper combo will work on the rear. | | | 04-11-2005, 02:00 AM | #4 | aka Stabby Join Date: Nov 2004 Location: Mead, CO Posts: 5,336 | GDB, someone posted that at some point, i asked for more details and/or if anyone had done it and heard nothing. do we have proof that this works or is it only speculation at this point? because if it works, i think we'd have a good number of people who'd be willing to do it (vented rotors and all would be nice in the back). i HOPE it's true, i'd just like to know for sure __________________ 1996 318ti, California package, 267k miles current mods: bilstein sports, bavauto springs, e30 m3 LCABs, solid metal ball joints, bavauto RSMs w/reinforcements, e30 3.73 LSD & halfshafts, supersprint cat-back exhaust, turner rear sway bar reinforcements, IE poly subframe & RTABs + camber/toe kits, powdercoated e36 32x front calipers, sport mirrors, H&R 28mmF/19mmR sway bars, x-brace, auto solutions SSK w/poly bushing upgrade, BMW CD43 head unit, DICE HD Radio w/iPod integration and "stealth" HD antenna, staggered style 68s, orange electronic TPMS, leather arm rest, JT Designs metal undertray acquired and awaiting install: heated seat kit, cali top switch relo, lumbar support kit, park distance control kit, heated washer nozzle kit, m-coupe rear subframe, trailing arms, differential, and halfshafts, m-coupe front/rear brakes with master cylinder, under hood light kit, mud flaps, rear sun blind, auto-dimming rear view mirror, tilt steering wheel retrofit, apexcone 5000K HIDs with 55W ballasts 2002 X5 4.4 Sport Package, 53.5k miles Current Mods: e46 m3 steering wheel | | | 04-11-2005, 04:32 AM | #5 | Senior Member Join Date: Aug 2004 Location: Tyler, TX Posts: 1,022 | Several people have done it to regular E36s, so I see no reason that it would not work on the ti. | | | 04-11-2005, 04:49 AM | #6 | aka Stabby Join Date: Nov 2004 Location: Mead, CO Posts: 5,336 | unfortunately, our rear is not the same as a regular e36, brakes aren't the same. if you know of someone who's done it though, i'd certainly like to hear details. __________________ 1996 318ti, California package, 267k miles current mods: bilstein sports, bavauto springs, e30 m3 LCABs, solid metal ball joints, bavauto RSMs w/reinforcements, e30 3.73 LSD & halfshafts, supersprint cat-back exhaust, turner rear sway bar reinforcements, IE poly subframe & RTABs + camber/toe kits, powdercoated e36 32x front calipers, sport mirrors, H&R 28mmF/19mmR sway bars, x-brace, auto solutions SSK w/poly bushing upgrade, BMW CD43 head unit, DICE HD Radio w/iPod integration and "stealth" HD antenna, staggered style 68s, orange electronic TPMS, leather arm rest, JT Designs metal undertray acquired and awaiting install: heated seat kit, cali top switch relo, lumbar support kit, park distance control kit, heated washer nozzle kit, m-coupe rear subframe, trailing arms, differential, and halfshafts, m-coupe front/rear brakes with master cylinder, under hood light kit, mud flaps, rear sun blind, auto-dimming rear view mirror, tilt steering wheel retrofit, apexcone 5000K HIDs with 55W ballasts 2002 X5 4.4 Sport Package, 53.5k miles Current Mods: e46 m3 steering wheel | | | 04-11-2005, 06:18 AM | #7 | Senior Member Join Date: Dec 2004 Location: Long Beach area Posts: 1,189 | Okay cool, thanks guys. Do you guys think that it would be wise to put 325is brakes on the front and M roadster brakes on the rear (first of all, do they fit?)? I need new brakes, so i figured "I might as well upgrade" haha Thanks again guys -Randy __________________ 97 Jet Black 318ti Sport. Not so stock anymore!....

I can tell you that vented rotors up front and the stock solid rotors in the rear have performed very well at the track. I think one needs to be careful about mixing brake setups. I'd be concerned about brake bias. BMW engineers know a thing or two about brakes. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 04-11-2005, 06:26 AM | #9 | aka Stabby Join Date: Nov 2004 Location: Mead, CO Posts: 5,336 | M roadster or MZ3 rear brakes will not fit without the trailing arms (hub is different ... ask J!m for details as i'm going on what he has stated before). if you're getting the trailing arms, then you might as well get the whole subframe from the M donor and then you're looking at a whole lot more than a brake job since i'm not autocrossing or racing mine, i am planning to just do the 325/8 fronts and stock rears (calipers are at the powdercoaters now). even if you could put the M versions on the back, i would think you'd want to put the M versions on the front (need the M spindles, M calipers, M rotors, appropriate pads ...). __________________ 1996 318ti, California package, 267k miles current mods: bilstein sports, bavauto springs, e30 m3 LCABs, solid metal ball joints, bavauto RSMs w/reinforcements, e30 3.73 LSD & halfshafts, supersprint cat-back exhaust, turner rear sway bar reinforcements, IE poly subframe & RTABs + camber/toe kits, powdercoated e36 32x front calipers, sport mirrors, H&R 28mmF/19mmR sway bars, x-brace, auto solutions SSK w/poly bushing upgrade, BMW CD43 head unit, DICE HD Radio w/iPod integration and "stealth" HD antenna, staggered style 68s, orange electronic TPMS, leather arm rest, JT Designs metal undertray acquired and awaiting install: heated seat kit, cali top switch relo, lumbar support kit, park distance control kit, heated washer nozzle kit, m-coupe rear subframe, trailing arms, differential, and halfshafts, m-coupe front/rear brakes with master cylinder, under hood light kit, mud flaps, rear sun blind, auto-dimming rear view mirror, tilt steering wheel retrofit, apexcone 5000K HIDs with 55W ballasts 2002 X5 4.4 Sport Package, 53.5k miles Current Mods: e46 m3 steering wheel | | | 04-11-2005, 02:40 PM | #10 | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 | i think the last thing you want is your rear tires to lock up before your fronts. i think the last thing you want is your rear tires to lock up at all. i can superglue a chair to my arse, but just because i can, doesn't mean it's a good idea. | | | 04-11-2005, 06:35 PM | #11 | Senior Member Join Date: Dec 2004 Location: Long Beach area Posts: 1,189 | Quote: Originally Posted by aceyx i think the last thing you want is your rear tires to lock up before your fronts. i think the last thing you want is your rear tires to lock up at all. i can superglue a chair to my arse, but just because i can, doesn't mean it's a good idea. | I was just thinking about that too. I wouldn't want to have the rears lock up haha. I think I might just go and put the vented rotors on front and keep the solid ones on the rear.

It goes through about 5 sets of front pads to each set of rear pads. Its a 2600 lb car and even with 900 lb springs in front under hard braking you can't add much bias to the rear without locking a wheel. And yes its bad if the rear locks first....

Stainless steal lines and Super Blue fluid were also added in the upgrade list... and I have plenty of brakes (even with out ABS). __________________ 1993/1996 325ti Also known as Tina | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
