Looks great! Nice work on repainting the pedals too since they always seem to get scuffed above the pads.

The car had small case 4.44 diff so i bought 188mm 3.46 LSD and installed it with fresh Motul oil




The new vs old small diff

Your 316i is very much like mine , almost nothing from a 316 is left in there hahaha.

V nice engine mounts , it seems you got better clearance from the front of the engine to the radiator tbh !

Car needs to go a bit lower , but i guess streets are very bad haha

btw , got the same equal length headers on my m52 .. only bad part is clearance with the engine mount for the front downpipe , but nothing that a custom exhaust can't do .

keep the good updates!

You need to make a thread about your car! :)

but yes these custom engine mounts give more clearance between engine and radiator,, thats why i can run fan shroud and orginal fan clutch


i'll definitely lower it a bit more when i buy adjustable suspension, but still the roads are not that great here :/

[Jean]

very nice build ! love to see more than just flashy wheels and steering wheel in the 'build" .

Cheers!

[Mazi!]

Same exhaust setup on my M52 car, just with stock OBD2 headers.
I found it a little loud for me, but damn it sounds good.
