Hey guys I'm currently converting my car from 4ac to ca18 det and need to do a break upgrade I have looked online and can't get a simple answer so what's the easiet front and rear break upgrade and the best value for money

There's no simple answer, except the one your certifying engineer provides.

 

I imagine AE86 front struts and brakes and whatever brakes your upgraded differential (if fitted) is fitted with, would get you a nice shiny firewall plaque.

Haven't yet upgraded the rear still wondering what to do there

Do nothing... they don't do much of the braking.

 

If you get a bigger diff like a T-series from a Celica they will come with larger diameter shoes and bigger slave cylinders.

 

I looked around the wreckers a few days back for small ventilated front discs and the best contenders were from a Suzuki Swift or a Mirage, the late 80s early 90s sort of era. Both of them would take some machining to get the discs to fit, and then the calipers would need mounting. The problem is the change in design for FWD that happened soon after the KE70s.

 

I'll look into it more as having something that works better but is light and small would be nice, rather than going for heavier struts to carry heavier hubs and heavier discs that take heavier calipers and the whole unsprung weight gets out of hand.

You will wnat a bigger than t diff to last long term behind a ca18det.
