Evasive is a great shop to go to... good reputation. It’s a JDM shop, but they do everything. (Unlike Corner3 garage who told me all they do is JDM cars and they refuse to see other cars... it’s not like the suspension on the Model3 is unconventional)
I was going to get mine installed at Auto Union Tuning in Huntington beach, but decided to DIY it myself (front is very similar to the Audi A4 since it has a strut bracket and rear is like a Porsche 911... with the right tools + lift it’s quick (I didn’t have the right tools or a lift so it took a little while). I’ll probably end up getting the alignment done at Auto Union Tuning.
I bet EAS can install it as well (European Auto Source) since they are also a KW dealer... they mainly do BMW’s, but like I said front is like an Audi and back is like a Porsche 911.
I think someone else on here used Antspec in Fountain Valley which used to be Cobb tuning which is also very good.
Lastly I was trying to get Malek at MRF engineering to do it since he is a very meticulous OCD type tech however he never returned my emails... he must be plenty busy doing rod bearing replacements for BMW M3’s.
