M35 Stagea, Upgrading to coilovers... Anything else I need?

[Tumble]

I'm about to take the plunge and upgrade my saggy OEM to a set of BC coilovers from Driftworks (UK)

Are there any other essentials I need to do  / fit at the same time.

It's my daily, and i'm not planning to slam it or go majorly stancey, but will be using it at my local drag race once in a while

I can get 4 wheel alignment and corner balance done at work..

A heavier rear anti roll bar...

Personally I'd take the opportunity to check over and replace worn suspension bushes while I was under there.

Thanks guys, both on my mental to do list as well. Can get full whiteline bush kit and rear ARB fairly easy in the uk
