If everyone had a million dollars to spend on a drift car they'd go out buying coilovers etc.
If you have enough money to spend on BC Ebay specials, might aswell get someone to make you up a set, specifically for your car. I was quoted about $1500 for custom ae86 front struts with height adjust, calipers, discs and pads. Decided I didn't really NEED them.
If you don't have that kinda cash laying around, to spend on a drift pig. then random short stroke munroes will suffice. I'm not saying theyre the perfect shock for the best drift performance, and that's what mark block collins use.
You don't need big bucks to spend, to achieve a decent car, is all I'm saying.
I haven't seen an ajps lock spacer, so I'm not 100% sure on those.
This spacer, the ends of the rack itself had offset threads, so the spacer wasn't perfectly flush with the diameter of the rack, and initially stretched the rack seal. The general population of racks might not be the same, again I don't know.
It's not really a problem, but potentially could case a leak if not checked every now and then. But then again, a ke70 manual rack is free from most guys on the forums.
EDIT: I'm running cut springs with short munroes in my car, No problems whatsoever, I've been in cars with coilovers all round and it's a much of a muchness. In my oppinion not worth the $1000 extra.
