Good day to all seniors n modders .... I have following problems and reading the forum makes me more confused as there are E90 335 which is a tick slight different from the E92 chassis.

Welcome E90 335 seniors guide as well but appreciate your highlight that you having the E90.

Appreciate your kind guidance / discussion / pointers to make my next step mod easier and prevent remod again ...

I have the following mods at this stage...

09. Ohlin rnt (stock Ohlin Springs)
10. Brembos 355/345 6/4 bbk
11. M3 front & Rear arms n links n m3 rear subframe bushing
13. Racing Dynamic Strut Bar front and rear


Questions

a) My rear anti roll bar snap off and broke ... I am looking for a good replacement. Seems there are a few recommendation : eibach, HnR, M3
- I am looking at going via M3 route but understand the front ARB is same thickness whilst the rear are 17 thickness ?
- Front unneccessary to be changed due to same thickness but to change the bushing and brackets ?
What would you recommend ?
b) Ohlin springs what is a good spring rate for very very spirited driving ?
c) What are good toe links (what is the purpose ?)
d) Is Camber plates necessary ?
e) LSD - Anyone has done it with welding and removal of our stock ? Any photos or videos links to see ?

I have the M Sport version of this e92 335 ...

Have any seniors fitted the E92 M3 Bonnet with the stock bumper without changing the fenders to M3 ?

Your kind advise is deeply helpful and very much appreciated from a newbie like me.
