Another one done - mine got finished today - and they let me get away with the WAAYYY too wide back tyres...

NSW has different regs as far as what's required, but if you're running a stock engine (A12-A15) I can't see any reason why the upgraded brakes and suspension should be an issue. Might find
that you'll need a bigger master cylinder to cope with the larger slave cylinders on the 200B struts. Sunny's had booster and larger cylinders, or try a Zed master cyl (i think 15/16
compared to 11/16 - much more stopping power).

In VIC it's based more on the car's ability to stop than whether or not it's as it came out from the factory - so long as it's a straight bolt in swap and no modifications are required to
make it fit.

I'm suprised you could fit 200B struts without hitting anything - your model must have different lower control arms than mine (although I'm not suprised as I think mine was a drum brake
front) My 1200 ute's running 120Y discs until I can get my skyline struts and 11.5 inch discs in (you thought your 10.5 inch 200B's were big).

I'd look at upgrading the master cylinder if you can afford it. I'm running the stock master on 120Y discs with a booster and I still think they're crap...
