I don't endorse laying frame personally and hellaflush/slammed is a bit try hard in my opinion but if do whatever makes you happy mate. That's the beauty of a forum, it's a group of people with a core interest in a particular thing but so many different ways of expressing it. Everyone has a different opinion etc
ANYWAY! I DO agree with Dann that you should have searched first but I was a noob too and used to start new threads on stuff I could have searched so I'm not going to judge.
I disagree with Sliq though. If you want to get that look, get a set of cheap YSR coilovers which will set you back a grand or less, or look for a set of BC BR series coilovers. They're pretty good and won't set you back a lot of money. There is no point forking out for Super Streets since they don't have a seperate collar adjustment for height and are pretty poor value for price. Factor in that you're going to be hell stanced so you won't be getting great performance out of the car anyway so you may as well go for cheaper coilovers. If you fork out the money for expensive JDM stuff, you'll never get to appreciate the quality of them.
Secondly, that car is running a set of Diamond Racing Steelies.
They are VERY cheap and very wide with insanely low offsets. You'll have to roll and pull your guards to get these to fit under and run very stretched tyres like this
Then run a LOT of negative camber to make them sit on that mental 45degree angle. That will not only make the car sit lower but also give it more 'stance'
I think to get more camber adjustment you can readily buy control arms with more camber adjustment?
Have to google that, it's been a while since I've seen them but I think you can pick them up on mania for cheap. From what I understand there isn't that much adjustment on the rear so you might need these.
I hope I've helped. Like I said, I'm not a huge fan of this look myself but I'm not going to judge other people for having different taste from my own.
Like mentioned earlier, join CRnet. Those guys are VERY stance oriented and love hellaflush/slammed etc. You'll get a lot of help there.
Good luck mate.
But one last thing. If you DO go through with this. you need to take protective measures so you down obliterate the underside of your car! Invest in frame rails, raised engine mounts and I think beatrush have a steel stone guard for your undertray.
This will raise your sump so you don't crack in on the ground, protect the engine from crunching on speed humps, stop the rails under your car for messing up. It should HELP protect you but remember you WILL damage your car!
Be sure to check out Mania for parts
http://www.mx5mania.com.au/ you can get YSR coilovers cheap there. I have a set and they rock!
Everything else, google.
but for a rough price breakdown you should be looking at
$1000 for coilovers
$600 for beatrush plate?
$400 for steelies
$600 for frame rails
$400 for control arms
whatever tyres you want
Prices are from my head with no research so could be way out. But that should get you started mate.
