I'm posting a thread here to link to the SR20 Forums group buy here.

Please see the related threads on the forums for your questions. Here's an e-mail off the group buy. If your interested click on the thread. This is probably the best way (on a budget) to go as far as a good B13 suspension that provides a good ride and great handling.


I've been getting allot of emails and PM's asking us to start another Hyperco B13 group buy. So here we go. As always, we'll need 50 pre-paid orders to get it off the ground.

Please only post here if you are seriously interested in purchasing a set. The group buy will stay open until we meet the 50 set minimum, so the sooner it's filled, the sooner we can get the order into Hyperco.

I'd like to thank Mike Kojima for helping us with the initial design parameters of these great springs, and for his continued support. Mike was kind enough to get a set of B13 Hyperco’s into the hands of Dave Coleman of Sport Compact Car Magazine, which lead to an excellent write-up and review in their April Issue.

We've probably sold close to 200 sets of these springs by now, and they have gotten almost universal praise. There are many, many reviews of them throughout this forum, and a few minutes of searching will more than likely answer any questions you may have.

The springs will be $289 + shipping. I will start accepting payments immediately, and if we do not receive the required number of orders in a reasonable timeframe, your money will be 100% refunded (minus any PayPal fees, if paying via credit or debit card). I will also put your name on the list if you don't have the money right now, but I will not hold back the order to Hyperco while waiting for payment, so if your on the list as a non-payer, and I get a paid order, you'll be bumped.

PLEASE UNDERSTAND... as with anything custom, this is going to require a little patience on your part. We can’t guarantee lead-time, but in the past, it’s been 12 to 14 weeks once Hyperco receives our order. So the quicker the payments come in, the sooner we can get the order to Hyperco, and the sooner they get in your hands.

Here’s some info from the previous B13 Hyperco group deals that you may find interesting.......

************************************************** *********
They fit 91-94 SE-R and NX2000's, the spring rate is 300lb front / 200lb rear, with a 1" to 1 1/2" drop and they work like a charm with KYB AGX's, or Koni’s. Don't be put off by the high spring rate, your car will ride and handle better than stock, and WAY better than ProKits! There were many people in the first and second round that happily tossed their ProKits in favor of these springs.

This is a special order, since Hyperco usually only makes springs for race cars (F1, NASCAR, CART/Indy, IMSA, SCCA Trans-Am, etc), and Hyperco makes them for us only in quantities of 50+, and by special order. Don't miss out!

If you're not familiar with these springs, please take a look at some of the excellent feedback we've gotten from happy forum members....

You just turn and the car goes where you want it, no body lean, no questions asked. You have no idea how fast you’re cornering until you look at the speedometer, then you don’t believe you're eyes. Wild. I don't know how they managed to make a suspension setup that handles so well, yet is so comfortable to drive in. Great job!

Hyperco Gen 2's are on!!
I must say I am VERY impressed. Outstanding product and I love the look!!

I finished the install of the new Hypercoil 300/200 springs, and can honestly, flat-out tell you that they are wonderful.

The ride is firm, but not harsh over bumps. Ride height is about 1 inch lower than stock, and one inch higher than ProKits. Just perfect, IMHO.

In my opinion, my SE-R feels like a totally different car than it was before. Even though the harshness is gone, the transitional abilities are a step above what ProKits had to offer. The car stays flat and goes where you point it.

Best *conventional* spring I've ever ridden/driven in any car. Just perfect.

It's been a few days now and an auto-x since I installed my springs. I also built and installed a rear STB at the same time. My comments are pretty much like everyone else, cornering is much more flat, turn in is crisp, and looks are great also.
Ride comfort isn't compromised allot, it really isn't that bad, bumps are not harsh, just a little more disturbing than stock. On and off throttle the car moves very little.

Auto-Xing, With the springs, AGX's and Azenis it was a HUGE change for the better. I was doing things with my car I didn't think was possible. I truly believe with a little more fine tuning I will be as good as a Koni/GC setup on a Classic.

This set really does soak up the big bumps and dips way better than the stock setup. The progressive spring rates seem to really help keep the chassis off of the bumpstops. Braking and accelerating are very much different from the 100,000 mile stock setup. Dive and squat are markedly reduced, and turn in is much sharper than the previous wallowy stock suspension.

Excellent springs!! Smooth install, great fitment. No weird noises or anything. Nice blue colour too.

Performance: Wow! Had my first auto-x on them last night, and understeer has been reduced hugely- I would say by about 70%. Car is now more prone to throttle oversteer - which is a good thing - much more neutral and predictable handling. The lack of understeer is just awesome.

FYI - the springs are on over *stock* dampers... can't wait to fix that!
