The car already has the e36 M3 brake setup, and stock rears. Any advice on a good pad combination? Will stock rear calipers and rotors hold up okay? Will get SS lines and RBF600 fluid. Also, tires. I'm planning 17x9 LTW5s with a square set up. I've been running a 135i that needed tons of work to eliminate understeer. Since the Ti is known for oversteer (e30 rear), and it will be partly gutted (very light in rear), is a square setup still what I want? Thanks for any experienced help! | | | 01-14-2017, 02:19 AM | #2 | Senior Member Join Date: Jul 2009 Location: US Posts: 315 | Welcome to the Org. While I cannot personally comment on the setup, a combination I am seeing for the rear is e46 325i rear calipers, 1 series rotors and http://srs-concept.com/product/e36-3...e-adapter-kit/ adapter. On my swap in the spring I will be running vented fronts, e34 rear calipers, SS lines and green stuff pads. Mine is a street car. I'm sure members with dedicated track cars will comment. Have fun! | | | 01-14-2017, 02:52 AM | #3 | Senior Member Join Date: Nov 2013 Location: Bresse Track France Posts: 535 | hi for the front i advice you the Pagid RS 14 or 29 with boa air duct and you can let the rear oem pads and disc i practice track with this config since 2 years on my 328ti without problems (ssline,rbf 660) for the wheels,it depends of your suspension, sway bar config ( and there set up) mine are 16X7 with slick michelin SA20 in 17X60X16 (200X45X16) and when they are at good pressure and temp,i can eat up the track | | | 01-14-2017, 04:19 AM | #4 | Junior Member Join Date: Jan 2017 Location: Florida Posts: 15 | Thank you, that helps. It's good to know that the rears should be okay stock, since it sounds complicated to improve them anyway. Yes, I will have ducting in the front. It sounds like you run a square setup for tires, and that's what I wanted to know. Mine will be 17s, but I'm glad I won't need to stagger them. | | | 01-15-2017, 09:07 PM | #5 | Member Join Date: Mar 2010 Location: Tacoma, WA Posts: 48 | I ran a 332ti with the 328i brakes up front which I'm pretty sure are the same as the 98+ 318ti. I had stainless lines, Stoptech fluid, and Hawk DTC-60 pads. Tires were 255 RE-11a's. The brakes held up just fine for 20-25 minute track sessions. | | | 01-16-2017, 12:50 AM | #6 | Junior Member Join Date: Jan 2017 Location: Florida Posts: 15 | Great info, thank you; guess I'll just upgrade pads for now and see how it goes. I've been debating 245 vs. 255 tires (square). The fenders are already rolled and slightly pulled, and I have camber plates; seems like 255 would be fine. But then, I HATE any rubbing. | | | 01-21-2017, 01:56 AM | #7 | Member Join Date: Mar 2010 Location: Tacoma, WA Posts: 48 | I had my rear fenders rolled and I think my wheels were 40 or 41mm offset with a 5mm spacer in front and I didn't have any rubbing. I didn't have my car very low though because I was running a standard height strut in front and going low didn't leave me with a lot of suspension travel. 255s were great but 245s might have been a little more responsive. | | | 01-21-2017, 03:15 AM | #8 | Junior Member Join Date: Jan 2017 Location: Florida Posts: 15 | I got a surprise today when I installed the PFC-08s that I plan to leave on the car. Because of the thicker (new) pads and the sliding caliper, the caliper did not clear the front wheel! They're Style 19s and won't be staying, but I have my first track day in it tomorrow 😳. I got super lucky and found a Goodyear store that also does a lot of customer wheels right near my house. They had hub-centric spacers in multiple sizes and at good prices! I only needed 5mm, but I'd read that Apex and DForce wheels would need a 12mm up front with 255s, so I went ahead and got that size now. I even had some longer lugbolts in a box, so those worked, too. Interesting though, I believe I'll need to do the rear brake upgrade listed above (e46/e82 bits and adaptors). While bedding in the new pads, I would EASILY lock the front wheels much too early. Yes, I want them to lock first (I don't use ABS), but there seemed way too much front bias. It was compounded by the ****ty current tires, which have little grip anyway. But, bring on the "test day" tomorrow! I expect slippery tires and too much front bias; hopefully that's all, and I'll know what I need to do. Thanks for all the help, guys. | | | 01-21-2017, 03:25 AM | #9 | Member Join Date: Mar 2010 Location: Tacoma, WA Posts: 48 | That upgrade kit looks pretty neat. I wonder how the analysis turned out in terms of bias when combined with the m3 front brakes. You may want to contact them and ask before purchasing. A lot of people "upgrade" the brakes on their street car under the assumption that bigger is better and say "it works great!" without having any numbers on the change to stopping distance, bias, fade, etc. You don't want to get your car out on the track and find that you spent money and ended up with something that works worse. | | | 01-30-2017, 07:35 PM | #10 | Senior Member Join Date: Dec 2011 Location: SoCal Posts: 702 | ^^^^ This! Very true. Since you have the e36 m3 front and its a track car, if you don't mind loosing the e-brake SRS-concepts also has a adpter to use the e36 m3 rear too - then you don't have to worry as much about bias. __________________ ![](image.php?s=ced60c18b782d27472b9a70173900511&u=11994&type=sigpic&dateline=1368758710) ***328ti Build thread. *** Even more important: SUPPORT 318ti.org!

NOW! | | | 01-31-2017, 04:23 AM | #11 | Junior Member Join Date: Jan 2017 Location: Florida Posts: 15 | My track test day went about as expected. The tires were hilarious, but the handling balance at least was excellent; plenty of controllable drift in third gear. The brakes...holy moly what a handful! I have no ABS, and the bias was very heavily to the front (and with **** tires, to boot). It was hard to be aggressive at all without locking up, and I destroyed two tires with flat spots (one to the cord!). Amazingly, I turned the same time as with my wife's modded 135i at this track. With tires and brakes, it will be much faster. So....I found a great close out at Tire Rack, and picked up a set of 245/40 17 Ventus RS3s. I had them mount them on their TR Motorports C2 wheels in 17x8.5. The whole package mounted, balanced and delivered was under $1200. I also did the SRS M3 adapter for the rear brakes. Rock Auto had great prices on parts, so I got new M3 rotors and remanufactured M3 calipers (in powder coated red 😜 ![Wink](http://www.318ti.org/forum/images/smilies/icon_wink.gif) for the rear. I went ahead and pulled the front calipers for rebuild and refinishing (red) as well. This will all go together by the end of this week. Monday and Tuesday next week? Sebring full course 👍😎. | | | 01-31-2017, 05:36 AM | #12 | Member Join Date: Mar 2010 Location: Tacoma, WA Posts: 48 | Great that you got the car out for some fun. You'll have to report back how the change in the rears affected the brake balance. Did you remove ABS? Mine still functioned after I did the swap, once I fixed a bad sensor that is. I flatspotted the hell out of a set of tires when I skidded 20ft at the end of an autocross course. | | | 02-08-2017, 10:01 PM | #13 | Junior Member Join Date: Jan 2017 Location: Florida Posts: 15 | Had a GREAT two days at Sebring! This brake setup was fantastic, and I no longer feel the need to fix the ABS (more likely to just remove it all). We even got some rain yesterday morning, and I was first and ONLY car on track for several laps. Ultimately, I managed a 2:41.05, which is four seconds FASTER than I've been there in my 135i. Yes, I need more power (or less weight!) to run the straights with all the Porsche GT2s and 3s, McLarens and Ferraris that were there (Hell, even my brothers e46 M3 with supercharger, which I also drove), but I'm not disappointed. I was able to hammer on the brakes lap after lap; no fade, no overheat, full control. I DID experience the dreaded e36 fuel starvation issue in Turn 17. The first time, it happened when I got to just over 1/4 tank, but as I got more brave with the car and pushed harder, it would happen as early as 1/2 tank. Anyway, new problem to solve. Two others that drove my car loved it, too. Gotta love budget speed! __________________ '97 318ti/S52 swap/e36 M3 Brakes F&R/SRS Rear Caliper Adapter/TRM C2 17x8.5 Wheels/245-40-70 Hankook RS3s/Rogue RSMs/BC Coilover and Camber Plates/large swaybars/partially gutted. | | | 02-11-2017, 10:03 PM | #14 | Senior Member Join Date: Dec 2011 Location: SoCal Posts: 702 | Quote: Originally Posted by Speed25 Had a GREAT two days at Sebring!

Its funny how many people worry about the e30 rear end and think its outdated but it seems a good set of coilovers/brakes and tires = a lot of fun still, and not too slow either. If you have experienced fuel starvation have you thought about oil starvation? Seems like its a problem from what I understand, people use s54 oil pump/dual pickup to remedy the issue. It might be worth looking into. __________________ ![](image.php?s=ced60c18b782d27472b9a70173900511&u=11994&type=sigpic&dateline=1368758710) ***328ti Build thread. *** Even more important: SUPPORT 318ti.org!

I'm going to check for the welded/wired/upgraded oil pump nut and oil pan baffle. I'll look into the S54 pickup, too. Yeah, I felt zero problems with the "deadly" E30 rear; I could put the car wherever I wanted and control it up to and even beyond the traction limits without issue. Frankly, I was looser with my bro's e46 (although with the supercharger, your right foot hangs it out at any time ). I hit a new snag two-miles from the house. Heard some noise up front, rough idle, then bang. Stock fan clutch fail with full blade deployment into the radiator. New radiator and fan delete with electric fan were on the list...now they're at the top. __________________ '97 318ti/S52 swap/e36 M3 Brakes F&R/SRS Rear Caliper Adapter/TRM C2 17x8.5 Wheels/245-40-70 Hankook RS3s/Rogue RSMs/BC Coilover and Camber Plates/large swaybars/partially gutted. | | | ![Reply](http://www.318ti.org/forum/images/buttons/reply.gif) | | 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 | | | |
