Performance tuning '13 M135i

Post by git-r2 » Wed Sep 20, 2017 1:52 pm

Hi there,
I have an early 2013 M135i and was wondering if there are any BMW parts I can fit to improve the performance of my car whilst retaining my warranty?
I'd like to fit the M4 arms to increase negative camber at the front - does this affect warranty?
Also, are there any lowering springs for adaptive suspension?
Can you confirm whether camber is adjustable on the back?
Are there any BMW tuning chips to increase power?
Please could you list any parts I could fit to make the car faster? (Not body kits )
Many thanks :)
'13 M135i standard.. and will remain so.. I promise... really.. will not modify... or abuse on track..
'91 R32 GTR... basically standard and unmolested... 497 @ rear hubs... never raced nor rallied : https://youtu.be/jhsX0elVG2k
+ some dullness

Good Afternoon,

We would need the car reg or chassis to look into this for you.

Fitting M4 arms will void warranty as they are not official for the vehicle in question.
