I bought my m3 ti with considerable front left suspension damage and both left wheels were bent. I fixed front suspension, front alignment is great, checked rear (non adjustable of course), and found my right rear toe was zero and my left rear toe was almost 5mm toed out! I inspected the control arm bushings, they didn't seem to have any play, and were just starting to gef cracks. I do think my rear subframe bushings are done, can these cause the rear toe to change? I was not sure. If the subframe bushings don't affect toe, then something is bent, nothing jumped out at me, so are the arms or subframe more likely to be bent? I don't want to waste money changing subframe bushings on a suspect subframe... Any advice from someone else that's been through this would be great... __________________ 96 Schwartz II 318ti M-Sport with M44 *SOLD* 95 Hellrot Red 318ti with S52 Swap (Mine) 94 Boston Green 325i Saloon with M50TU (Hers) 68 White VW Bus Camper (Parts Bus) 71 Pink VW Bus Westfalia (The fixer upper) | | | 09-25-2011, 12:15 AM | #2 | Senior Member Join Date: Apr 2006 Location: Oxford, Ohio Posts: 868 | I'd guess the trailing arm. | | | 09-25-2011, 06:23 AM | #3 | Senior Member Join Date: Jan 2010 Location: Oakland Posts: 187 | Any other votes? __________________ 96 Schwartz II 318ti M-Sport with M44 *SOLD* 95 Hellrot Red 318ti with S52 Swap (Mine) 94 Boston Green 325i Saloon with M50TU (Hers) 68 White VW Bus Camper (Parts Bus) 71 Pink VW Bus Westfalia (The fixer upper) | | | 09-25-2011, 10:00 PM | #4 | Senior Member Join Date: May 2006 Location: 43609 Posts: 3,425 | Whether they look good or not, the bushings are likely shot and worn in. Even brand new, parts wont always put it in spec let alone, equal out on both sides and give you a 0 thrust angle. You need to install toe and camber kits to place the rear where it needs to be per your alignment specs, whether custom and lowered or to OE. Theres no real way around it. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone 1998 Schwartz II sport 318ti - M50TUB25/5 | | | 09-26-2011, 03:37 AM | #5 | Senior Member Join Date: Jan 2010 Location: Oakland Posts: 187 | Like the Ireland engineering kit? Or is there something better? __________________ 96 Schwartz II 318ti M-Sport with M44 *SOLD* 95 Hellrot Red 318ti with S52 Swap (Mine) 94 Boston Green 325i Saloon with M50TU (Hers) 68 White VW Bus Camper (Parts Bus) 71 Pink VW Bus Westfalia (The fixer upper) | | | 09-26-2011, 03:42 AM | #6 | Senior Member Join Date: May 2006 Location: 43609 Posts: 3,425 | as a certified alignment tech, theyre all the same, just pricing differences. It all depends on your install. You can weld in the camber and toe plates to accomodate for being lowered, to gain more positive camber and get toe to a feasibile spec. Or if its a dd and youre trying to save tire life, compromising handling, you can adjust accordingly. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone 1998 Schwartz II sport 318ti - M50TUB25/5 | | | 09-26-2011, 03:54 PM | #7 | Senior Member Join Date: Jan 2010 Location: Oakland Posts: 187 | It is my daily, and it just about finished ruining a setup of Z1 Star Specs, as the shop that did the alignment after I repaired the front end, failed to mention there were SERIOUS rear alignment problems. The car does see Infineon every couple of months, so it does go to the track, the alignment specs aren't hard to figure out, just hard to acheive with no adjustment possible. I only asked about the weld in kits, as we installed a IE kit on another more stock LOW TI and he came back and the rear alignment had shifted, so either the kit is bad OR my mechanic didn't tighten the bolts and or the customer bumper something? I'm also trying to figure out some better spring setup. I have CUT (I know WTF? right) front stock M3 springs and 4 cyl Ti H&R Race rear springs. I'm thinking about doing front H&R Race springs and some stock rear M-tech springs from a 4 cyl car? I can't/won't put coil overs on, as my commute is 70 miles round trip 5 days a week and they won't last. Any spring combo suggestions? I have adjustable Koni Sport shocks on all four corners... __________________ 96 Schwartz II 318ti M-Sport with M44 *SOLD* 95 Hellrot Red 318ti with S52 Swap (Mine) 94 Boston Green 325i Saloon with M50TU (Hers) 68 White VW Bus Camper (Parts Bus) 71 Pink VW Bus Westfalia (The fixer upper) | | | 09-26-2011, 04:16 PM | #8 | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 | There is a good thread in the bimmerforums track section discussing why the eccentric tabs/bushings won't stay put. Basically once adjusted, the eccentric bushings fight each other because they are no longer coaxial. They also believe that once the spring coil binds it creates a fulcrum that places more stress on the rtabs which causes the alignment to move. They are specifically talking about SpecE30 cars which use H&R race springs. As most of us know, H&R race drop the car way too far with too little spring rate to compensate. This lets the springs coil bind fairly easily. Supposedly, Ireland Engineering is designing a new weld in kit that addresses these issues. http://forums.bimmerforums.com/forum....php?t=1683367 http://www.e30tech.com/forum/showthread.php?t=107867 __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 09-26-2011, 04:23 PM | #9 | Senior Member Join Date: Jan 2010 Location: Oakland Posts: 187 | is there a better spring with a higher rate? __________________ 96 Schwartz II 318ti M-Sport with M44 *SOLD* 95 Hellrot Red 318ti with S52 Swap (Mine) 94 Boston Green 325i Saloon with M50TU (Hers) 68 White VW Bus Camper (Parts Bus) 71 Pink VW Bus Westfalia (The fixer upper) | | | 09-26-2011, 04:27 PM | #10 | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 | Coilovers, you can have any spring rate you want. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 09-26-2011, 04:56 PM | #11 | Senior Member Join Date: Jan 2010 Location: Oakland Posts: 187 | Can't do that. It doesn't look like anything came of the spec E30 guy and hsi rear alignment moving issues... __________________ 96 Schwartz II 318ti M-Sport with M44 *SOLD* 95 Hellrot Red 318ti with S52 Swap (Mine) 94 Boston Green 325i Saloon with M50TU (Hers) 68 White VW Bus Camper (Parts Bus) 71 Pink VW Bus Westfalia (The fixer upper) | | | 09-26-2011, 05:02 PM | #12 | Senior Member Join Date: Jan 2010 Location: Oakland Posts: 187 | Turner says these dont fit 318ti's, I bet they do. Has anyone tried them? In addition to my rear alignment problem, I also have a cut spring and 4 cylinder car spring problem... Seems like these might help the rear not bottom out, which seems is what the problem is with the Weld in IE adjusters? __________________ 96 Schwartz II 318ti M-Sport with M44 *SOLD* 95 Hellrot Red 318ti with S52 Swap (Mine) 94 Boston Green 325i Saloon with M50TU (Hers) 68 White VW Bus Camper (Parts Bus) 71 Pink VW Bus Westfalia (The fixer upper) | | | 09-26-2011, 06:53 PM | #13 | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 | ^^^^Not sure what you are referring to at Turner... I bought used TC Kline rear springs and ran them without the adjusters (just stacked spring pads) and that let me pick my ride height and spring rate. Felt way better than the H&R sports. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 09-29-2011, 03:54 AM | #14 | Senior Member Join Date: Jan 2010 Location: Oakland Posts: 187 | __________________ 96 Schwartz II 318ti M-Sport with M44 *SOLD* 95 Hellrot Red 318ti with S52 Swap (Mine) 94 Boston Green 325i Saloon with M50TU (Hers) 68 White VW Bus Camper (Parts Bus) 71 Pink VW Bus Westfalia (The fixer upper) | | | | 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 | | | |
