Hope this info helps:JIC is 15way adjustable, with threaded spring perch for height adjustability. it also comes standard with camber plates for all 4 corners. big thing is that the 240 has problems lowering effectively because of the shock body must be shortened or you will be on the bumpstops all the time. the solution is to get a shorter shock body, which tein has, but the problem comes again because of the lowered compression travel. JIC solves both by using a threaded shock body, allowing you to shorten the shock body without sacrificing compression travel. the spring rates are 447fr and 335rear. I am pretty sure you will be good with this. the tein offers 448f/336r, but you won't feel the diff. of a pound. I am going to use JIC for these reasons, and because you can order strut bars from them also, and it's usually better, though not required, to go as much with the same company as possible, as thier equipment is tuned together. sport compact car chose this setup also, and you can find out more at
http://www.sportcompactcarweb.com, and do a search on project 240, then select project sylvia. it comes up as no info. if you just punch in project sylvia, don't know why.
Btw, if you do a thorough search of the board, you will find that tein's are good, but after getting them, people would still like to upgrade to JIC. It's never the other way around. tein he/ha: just over a grandJIC flt-a2: 1599 not sure about your rims and offset, but the JIC is supposed to be able to work with this. I'm not sure about that part though.hope this helps!
