SUPER COMP SPRINGS PASS OUR 100 DOLLAR BILL CLEARANCE TEST WITH 7 QUART NISSAN RACING OIL PAN (SEE PHOTO)

1st PHOTO: Shows a typical Super Comp install complete with our competition sway bar.
Absolutely, positively no alignment, safety issues or geometry problems or wheel fender interference using this lowering kit.
Approved and exclusively used, as the spring of choice, by Spriso Motorsports on all their SR20 conversions.
Rate of this spring is 860 lbs - Length 8.750".
You must shorten your original tall bump stops or buy our short comp bump stops, part number 1890 and shorten them .375 to provide the proper clearance needed between the top of the bump stop to the bottom of the upper control arm. Not shortening the bump stop will cause the bump stop to bottom out creating a harshness in ride. You can also use our part number 2174 urethane spacer under the springs to add more clearance or to adjust the height for street or race use. Free to those who purchase a set of springs, just ask and we will add them into the order.
Using the same vehicle, we completed a extensive, controlled, proper and fair test of this spring as compared with one other manufacturers product currently on the market.Our spring is lowest of them all without question!
Great for racing or on the street!!
Note: Available in Black only.
Special Note For 510 Owners: We have detailed instructions and a superb review from Dave Witt who installed a set of our springs. Just ask and we will send it out with your order.
3rd PHOTO: and following 2 photos are of a non restored, unmodified, 3rd owner car. We wanted a car that was very original. This car has stock Nissan springs front and rear.
The 2nd set of 3 photos were taken with the Super Comp springs installed. These photos were lifted from the Super Comp Spring test where ride height and drive ability were compared of each spring currently on the market. This comparison test was made with great care and consideration eliminating any variables that would render the test inconclusive or incorrect. Everything from sagging front and rear leaf springs, tire pressure and profile, mileage and spring settling were considered during the test. The original Nissan comp claim of a 1 1/2 drop from stock height is explained in the test as well. The 8 page test with photos and detailed explanation of the stringent testing procedure are provided when you purchase the springs we sell.
Springs were tested using a Larson Flash 36 load tester rated with a 5,000lb cell which cost $90,000. Not tested on a $1,000.00 Summit Nascar cage less spring tester. Wire hardness tested on a US made Newage calibrated Brinell hardness tester 7000.
