Depends on what else you have done to your car, but if the springs are the only modification, it looks like you'd end up in BSP.
If you're a serious SCCA Solo competitor, you probably already know this and know that it takes a lot more than a set of lowering springs to build a class winning car. You might consider staying stock.
If you're not a contender, don't sweat what class you're going to be in! Run what you brung, enjoy your car and have a good time!

Yeah I stayed stock with the Z for a whole season before moving to Korea. My experience with BSP is that there are some sick cars and drivers competing.

As far as mods, I have the Stillen Gen 3 intake and catback waiting for me when I return to the states. Whatever class I'm in I'll have fun even if I'm in dead last.

You should be warned that Stock class is pretty intense at the National level and the talent is abundant and the cars aren't really stock at all.
I did an "arrive and drive" at the 2000 SCCA Solo II Nationals in a 1998 Acura Integra Type R that had won the National Championship the year before. It was prepared with re-worked shock absorbers, a wild alignment, different sized tires front and rear, a cat-back and any other thing that could be adjusted or modified and still stay within SCCA Stock class according to the rules!
Stock? Yeah, right! :rolleyes:

hey guys...how long should i wait for springs to settle before getting an alignment??

No more than a week, if that long. If you have driven it a couple times and the car has been allowed to sit for a little while between drives, they should be settled at that point.

great, thx!

Decision made. Gonna pick up a set! Thanks for the info people!

You will love them, I still can't believe how much of a positive difference it made to the overall handling dynamics of the car even with my Stillen sway bars set to aggressive.

My set are on the way!! ;)

Rides definitely stiffer than stock but still very comfortable. Handling is much improved and you definitely notice the lower center of gravity. Gonna upgrade to eibach sways in a few weeks.

Head hurts...
 

Note: I do not wish to offend anyone about my thoughts on some examples used here. Plus, this is going to be the first time getting lowering springs.

Concerning functionality, I'm all for improved ride quality and handling with these springs. In terms of looks, I want to make sure the gap is narrowed without ending up with a "ricey" impractically sunken look. My car currently looks silly with 255/35 & 285/30 tires at stock height. There's more than a 3 finger gap. Other than that, it drives fine.

In regards to a 1" drop for the rear, I'm a bit confused by the way the rear end is lowered. However it may be perspective differences in the way the photos were taken. I've seen a few pictures of cars with 305 tires at stock height showing some significant wheel gap. Osiris, with 305 tires and Swift springs, has a very nice gap. However, his springs hasn't settled yet. 98intrigue also has 305 tires, but with H&R springs. His rear tires look tucked in making it appear to be lowered by more than 1". Then there's pictures of the Sport and Nismo cars with Swift springs with nice wheel gap.

I'm still debating about 285/35 versus 305/30 tires to handle extra power from FI, but I'm worried about a couple of things:
- Funky tucked in look.
- F.I. exhaust cans scraping. At stock height and 285/30 tires, the cans scraped on occasions such as backing out of the driveway.

Anyhow, I'm planning to get new tires when the Swift springs get installed. To be safe, it'll be 255/40 & 285/35. For aggressive, it'll be 275/35 & 305/30. :icon14:

Heya,

As far as settling, i don't anticipate the rear settling more than another .1 or .2 inch for a total of 1 to 1.1" Also, i think the wheel/offset also has a huge impact on the appearance of the gap. I think some others running 305's have them installed on stock wheels. As for mine, i have them on the Volks with 22+ front and +12 rear offsets bringing them closer to the outter edge of the wheel well and making the gap appear smaller.

Let me know if you want me to take shots of different angles.

Thanks! My GT-S rear offsets are +8mm, and I still have a few more months to decide. Please update us with new photos once your springs has settled after you get your alignment done, if necessary.

Also, the camber will affect how the drop looks for the reason that Osiris noted regarding how flush the wheel is with respect to the fender.

Do these springs put anymore stress on your stock shocks? Should I be changing my shocks too?
