Hello 2Addicts,
A momentous event has occurred. I’ve paid off my automobile!
A 2015 M235i 8-spd ZF RWD Mannequin
Now to start out planning modifications
Simply kidding.
First it is time for attending extra Autocross occasions and getting an actual really feel for the automobile.
I have been autocrossing the automobile on and off since I acquired it together with my CS-lite prepped S2000, however just lately I moved to NYC and that’s simply not an surroundings I wish to carry an S2000 into plus I must pay to park the 2nd automobile. So I am seemingly going to promote the S2000 and “for enjoyable” construct an STU-lite M235i. I do know its not going to win NATs when E9X Ms can mount 10.5″ wheels and 285 tires, however I’ve seen only a few M235i get prepped for STU. I’ve seen just a few 135i get prepped as properly and with each vehicles now being ~$20k vehicles I determine others possibly trying to mod up their M235i for Autocross so why not begin a construct thread about it.
I have already got a little bit of a begin. Present Mods are:
Vorshlag Camber Plates
Alignment: 0 toe up entrance dialed to 2.4deg Camber for the Road/AX compromise. Just a bit toe in on the again with 2.1deg Camber
BootMod Stage1 93 tune
CSF Intercooler
Evolution Racewerks Cost Pipe
225/40/18 RE71RS 200tw tires on Inventory Rims
For Subsequent Yr’s Season going to taking a look at some upgrades. Plenty of analysis nonetheless to do right here. For this yr I am actually attempting to concentrate on the driving and determining what the automobile wants probably the most. The above is the order I am going to seemingly make extra enhancements to the automobile in. Ideally I would do the upgrades , but when not nonetheless one thing to be stated for making tweaks step by step and seeing how that modifications what the automobile wants tweaked to maintain it balanced.
In approximate order:
LSD – Most likely M-Efficiency, however I could give Bimmerworld or DiffsOnline a name relating to that although
Coilovers – possibly Ohlin Highway and Observe, seen good critiques on the F3X boards about them
Hotchkiss Entrance Swaybar
17×9 or 18×9 Wheels – Going to be a bit tough, taking pictures to get 255 sq. on the automobile
Anyway on with the Autocrosses!
Regardless of not being an M2 the automobile is sort of enjoyable to autocross and I like to recommend anybody take their M235i and provides it a strive. The quick wheelbase and good torque supply actually make the automobile fairly nimble for a luxurious barge and actual quick in additional open sections. With inventory wheels it’s an train in endurance within the turns, however coming from an S2000 getting on the fuel and launching it down the extra open straight areas of the course feels wonderful. The 200tw tires undoubtedly assist with grip ranges given the open diff. This is an occasion I did just lately with Philadelphia SCCA.
I went within the first group so I did not get a lot probability to watch different drivers’ traces. Between the first Flip-around and the 2nd I noticed some drivers take a barely wider entry up the hill simply scrapping one of many partitions on their method up the hill. That line would have prolonged the straight just a few tenths extra. Evaluating my fifth run to my sixth I discovered giving up simply 1mph extra velocity actually allowed the automobile to turn-in barely earlier and start the exit onto the straightaway up the hill towards the 2nd turn-around earlier. Undoubtedly really feel the automobile struggling a bit with inside tire grip because of the lot being a little bit of an inverse bowl, however utilizing third gear retains this largely below management.
