1) Most instructions should have pics of the area's that need to be applied but I would assume the top mounts etc.
2)yes the bottom bracket will adjust the height and the other adjustment under the spring will adjust the spring preload-how firm the ride will be etc.
3) Some shocks are left or right specific but if they are it is usually stamped on the struts somehwere
4)yes
5)If you are changing the height, yes.
6)yes
ISC N1 coilovers = $1499
If your just after springs we can supply whiteline, king, tein, etc
As above, don't drop it to much if your just changing the spring as you will bugger your stock shocks and the ride wouldn't be overly comftable either.

pretty much sums it up!! I think people have taken the last 2 years for granted though with the yen being at 95-105...it has never been that high before and who knows if it ever will be again...
(fingers crossed), Ryan
Depending on what mods you have you may not need either a power fc ($1000+) or a remap ($550+). Your best bet is to call up Shaun from boostworx (+1) and see exactly what he recommends as the most cost effective solution to get what you want from your rb25det.

usually clockwise is harder and anti clockwise is softer. Just set it all the way one way and then again the other way and youll soon find out what way is soft etc.

I'am running 235/40/18 but should be running 255 or 265/35/18 (got the 235/40/18MAZ1 for an extremely good price though).
Pics below as requested.

Hope you wern't reffering to ISC? ISC is a non generic Taiwan coilover company. Made in the same country as many of the "jap" branded coilovers on the market...
Ryan
If the most recent thing that was installed was the coilovers then perhaps that is the issue? Either the top pillowball or the spring? Other then that if you lowered the car when you put the coilovers in you may be putting new stress on worn parts that you wouldn't have noticed before.

Nice program^^^. How did it create the map of mallala? Through google maps etc or just traced your path? You planning to head out agin soon, definetly want to see this thing in action!

As above, I have about 3-4 mates on these forums that are police officers with imports...heck I even used to sponsor one.
I would say there are alot more that surf these forums especially nissansilvia.com being as it was the most viewed auto website for the last couple years etc.
