what size of mounting plate should i be using

[ramresh]

i am trying to lower the car with after market spring kits on my 2000 Audi S4

I am not sure about the size of the mounting plates that i should use

I wouldnt advise touching much on suspension on 11 years S4.

havent you paid already enough to Audi that you like to invite more problems????? If you are a new owner then drive for few months i am sure it will occupy you more and you wont have time and money to think these extra bits.
