370mm/345mm brake upgrade question.

cesare87 · 09-08-2016, 12:10 PM

Quick question guys, when upgrading to the 370mm calipers and discs, do I need the 370mm backing plates as well?

Same question but with the 345mm rears, new backing plates needed to match or can I use my existing ones?

Ta,

For fronts definitelly need them.
For rears depends the car.
If your car is x16i then you need them but if your car is x28i then not.

Thanks for the reply.

I'm guessing I shouldn't need them on the back of a 35i?

No need .. already equiped with big plates..

The other alternative is to trim your existing backing plates as well.
