lol, well thanks for being willing to listen and not getting bent out of shape when someone questions if you know what your talking about.
I'd encourage you to read... a ton... but be weary of reading too much of things like this thread. People will be so quick to say "OMG get 10/8 coilovers! stiffer!" when they are never gonna be on a track and its not too hard to go stiff enough to lose grip on bumpier surfaces like streets and mountain roads.
Hell even KTS at 8/6 loose some grip on roads that aren't ideal. Also look at the stiffness of the the springs, not just the drop... stiffness will be given in the force (quite you physics majors, close enough) required to compress the spring a certain amount. Typically stuff for imports will be in killograms per mm of compression, so the springs on the front of KTS coil overs take 8 kilograms of load to compress 1 millimeter. Domestics are often given in pounds per inch of compression. Stock on a 240 is about 2kg/mm front and read iirc, should be in the stickies at the top of the forum.Be sure not to make the mistake of comparing spring rates from one type of car to another... Honda spring rates will seem crazy, because the spring is further inboard so the suspension arm acts as more of a leveler, so a stiffer spring is needed to give the same rate at the wheels.
zerothread/11638This is a good thread, with a fairly comprehensive list of 240 spring rates. If you have S-tech those actually don't look too bad...
for a street setup RSR race springs, a GOOD pair of adjustable shocks, ground control coil overs, camber plates(if needed/wanted), adjustable swaybars (I have whiteline, and progress, progress is damn good... but i dunno if they are still made? I couldn't find them thats why I went with whiteline)...
AND MOST OF ALL GOOD TIRES (all suspension works just seeks to optimize the tire...it is the ONLY thing holding you to the ground, remember that.)
I think the above would kick some ***. I haven't owned or even ridden on the RSR springs, but the rates look good... and some respectable guys here have spoken highly of them.
Of all the areas I would try hardest not to skimp on shocks or tires. Most the other pieces are just metal. Springs you gotta trust that the maker is giving you good rates... but thats easy enough to just steal from another company, and the manufacturing isn't overly difficult. But shocks... quite a bit to skimp out on or mess up in manufacturing, not so much so that they will break... but dampening the spring can be a demanding job, and the smoother the load you can put on the tire the better.
Tires also are incredibly complex, your best answer is to say **** tread wear and pick up something like a Falken 615, or the Hankook RS-2 (did I mess that up?)
I just finished up reading about 75 pages of pretty damn detailed info on tires...just to give you an idea of how complex they are...and that doesn't even include going into the chemistry of tread compounds.
I think I have rambled sufficiently for now....
