I'll admit I blattently plagerised this from a guy that go's by Mr Breeze but these are some things you should know befor lowering a bay. Be carefull and do it the safest way possible.
The Front:
#1 Drop spindles up front , $250-$350 depending on drop and maker, try Nate at http://www.wagenswest.com
They will leave you with an almost 100% stock suspension.
#2 Yank torsion bars out of the front beam until desired height it reached.
This way you lose ALOT of suspension for every 1/2", up to about 4" lowered when you have none.
#3 Adjustable front beam. This is lots of work, but allows you to select what ride height you desire and set it back to stock if you like. Not cheap, and not as easy since the whole front beam must be removed and cut / welded. You can find these in your neck of the woods.
#4 There are some suppliers in the UK who have some other things such as Coil overs shocks, but they're expensive and I dont have any first hand knowledge. Here's a link of a supplier on your side of the pond. http://www.bluebird-type2.co.uk/suspension.htm
The rear:
#1 Take the rear suspension apart and turn the springplate on the splines. Lower as much as desired, but again, you lose some suspension travel.
A caution added by Karl - The more you lower the rear by adjusting the torsion bars, the more negative camber you put in the tires. They will be riding on the inside edge and be severely tilted in
#2 Drop plates. These are a metal plate that bolts to the spring plate and raises the point where the axle bolt on UPward. Lowers the rear, and theoretically leaves the suspension stock. Never tried them.
#3 You guys in the UK again have some neat stuff.
Like I said I appologize for taking this info from somewhere else but there's good knowledge here.
