I would have to agree with the majority.

The driving you are talking about doesn't seem to warrant LSD especially at the cost.

From LSD to your mention of Dinan products and long lasting of a car, it sounds like you want to keep that warranty and also not push the car too hard to where it would prob last 10 years.

I would say go with the stage 2 tune and CAI. I love it. and yeah you can push your car faster for far less, but I for one do not know how reliable those tunes are over a 10 year span. Even dinan is limited in the warranty per years.

perhaps you might want to just upgrade some suspension aspects of your m235i such as sport springs, etc. instead of dropping 2k +.
