135i M Sport

[Snowboy]

I've just bought one.
(2009 model)

Apart from ditching the run flats at the earliest opportunity, is there anything else anyone can suggest that I need to know?

Are the run flats really that bad?
The ones fitted seem to nearly new.

If I turn of the traction control will I instantly crash and die, or will I just slide around a bit grinning?

Great car - I bought one after running an E90 M3 and found it a better overall package for the real world.

Run flats aren't that bad - I'd keep them until they're spent to be honest.

I think run flats are tolerable in summer but are plain dangerous in winter ( Poor traction, poor lateral grip and long stopping distances ). The difference when I swapped from 19" Bridgestone RFTs to 17" Dunlop Winter Sport 3Ds, on my E92 335i, was night and day. Ride on the stiff walled RFTs is cart like too. imho of course.

Taking the run flats off the front of the 335i as they wore through the inner edge (the rest was 5mm though) was the best thing i did. The car actually goes over bumps/speed bumps now and grips so much better.....just got to wear out the backs now though!!!!

Sorry to hijack the thread... I'm looking at some winter rims and tyres for my 335i and didn't know if 17" alloys would fit, but I take it yours fit no problem? Out of interest where did you get the alloys?

I think 17" Style 188 were standard UK fit on 335s, as per the info and photo in the following link.

http://www.carfolio.com/specifications/models/car/...

Wheels front 8J x 17
rear 8.5J x 17
Tyres front 225/45 R 17 91W
rear 225/45 R 17 91W

I bought refurbed style 158 alloys from here earlier this year.... http://www.bmautosport.co.uk/showroom/product_info...
Refurb quality was very good as was their service. If you're fitting winter tyres, ask if they'll do rims only ~ they did for me.

get the clutch delay valve (CDV) modified so you can change gear properly and fit E90 M3 bushes in the rear subframe and get the M3 front lower control arms.

then last but not least head over to Birds and pick up the full B1 suspension set and quaife LSD...
