In Street Prepared it is done by which vehicles are listed on the same line in the Solo rulebook. The 240/260/280 are all listed on the same line so you can update/backdate between all models. Engines, transmissions, or transaxles must be done as a unit, but you can swap them between years. Knowing this, how close do you think a SP 280 can get in weight to an SP 240? Thanks!

Why are you not able to swap out the bumpers? The cars are listed on the same line under the Street Prepared listing so it should be a legal update/backdate, no? Also, I thought I remembered hearing about people removing the undercoating from their SP car, but I may have been thinking about IT prep ( guess I'm on too many mailing lists )

Is the weight difference from things that can be removed, replaced, or taken out through ud/bd? Undercoating can be removed, is there other sound deadening I'll be stuck with? I know the diff can be changed, and some of the weight is in the bumpers. Seats will be swapped out for race seats at some point. Are there other things I'll be looking at changing? TIA!

OK, so the 240Z I was looking at didn't pan out, but I've got a line on another car. A friend has a (78?) 280Z sale that doesn't run.Since you can update/backdate in BSP, is there any significant advantage to starting with a 240 over a 280? I'm assuming the best way to start would be to ditch the stock FI system and go carbureted. The body and interior are in good condition. He doesn't know how much he wants for the car, he's just looking for a fair deal. I don't want to low-ball him, does $500 sound low, high, or about right? Thanks again for the info!

My first post: I'm interested in changing autocross classes next year. I've been running an H-Stock Civic for a couple of years but I want to move to something I can modify and that is RWD. BSP has always looked like a lot of fun, and I've always regretted selling my 73. I've got a line on a (relatively) rust free 240Z that is running, so my plan was to start with the suspension. I know I won't be competitive my first year in the car, 2002 will be spent building the car and learning how to drive it. The car will see (very) occasional street duty, but the ride quality is not important. I'm figuring I'll end up with coilovers in the long run, but to start out I'm thinking springs, Koni's, poly bushings, and adjustable sway bars. What spring rates should I start with? How much can I lower the car without messing up the suspension geometry? How much camber will the car pick up when it is lowered? Are camber plates absolutely necessary, or can I get away with doing them later? Are there any rear ends that I can ud/bd that have a decent LSD? I know I'll have to put in an aftermarket one eventually, but the budget is pretty tight. Also, what rear end ratios are available? Is there any way to ud/bd 4 wheel discs and is this mod worth doing? I've heard the heads from some years breathe better than others, what years should I look at? I'm guessing that custom FI is the ultimate way to go for power, but since I'm poor what carburator(s) is/are recommended? What would you recommend for wheels and tires? Will a 13x10 with 225/45/13 Hoosiers (you know, CSP wheels) be enough tire with the stock motor? I'm guessing I'll need to put more rubber down when I start making more power, what wheel/tire combos are the other BSP cars running? If there is an online resource that already has these answers just point me in the right direction. Thanks for any help you can give me.
