BC Racing Coilovers Honda Prelude (92-01) 30 Way Adjustable Suspension

BC Racing Coilovers Honda Prelude (92-01) 30 Way Adjustable Suspension

Fitment Information Honda Prelude (1992-2001) All NOTE: Any BC Racing kit modification such as custom spring rate, upgrading to swift springs or that is not regularly stocked as an extreme low kit will require an additional $150 invoiced to you by our orders team after you place your order.  Specs & Features 30 levels of dampening adjustable. Spring Rates: 10k front and 5k rear. Front Camber Plates: No BR Series - Single Adjustable Linear Coilovers 1 Year Warranty when purchased through Redline360 (Authorized Dealer) Fully Rebuildable Linear Piston and Damping Curve Mono-tube shock design Includes a full set of 4 coilovers Genuine BC Racing coilovers Optional Swift Spring Upgrade All springs are not created equal. The diameters and spring rates may be similar but the process of manufacturing springs plays an enormous factor in how springs perform. Swift springs are manufactured using superior engineering and have moved quickly through the ranks of motorsports and some of the world's most reputable races. Swift's impressive motorsports history dates back to 1998 with the Nissan Skyline GT-R in the Super Taikyu Endurance championship series in Japan, then championship teams in Le Mans 24hrs, Nurburgring 24hrs, Super GT (JGTC), Super Taikyu series, D-1 World Grand Prix, F3, F3000, Formula Toyota, and many other world class races. Swift springs are the lightest in weight, strongest in durability, and highest in linearity of any spring on the market. Cold wound Thinner wire diameter with fewer coils Lightest magnetic metal springs available on the market Swift Metric Coilover springs feature the highest linearity of any spring Wide stroke range More linear usable stroke range than other springs on the market Limited lifetime warranty against spring sag Industry leading spring response Superior spring compression speed Responds more quickly over undulating road surfaces Tires have less tendency to skip Improved traction Decreased tire temperatures Product Description   The ultimate street coilover!  BC Racing has been known amongst performance enthusiasts to manufacture one of the best coilovers on the market.  There is almost no equal to the level of performance, adjustability and ride quality you receive from BC Racing Coilovers.  BC Racing makes it easy to replace your factory suspension with a full performance coilover system by including everything you need in a comprehensive kit.  These coilovers come with an adjustment knob that makes it easy for you to set the coilover dampening to your specific needs and adjust compression and rebound together.  You can also adjust how low you want the vehicle by adjusting the shock body, as opposed to cheaper kits that make you compress the spring in order to lower the vehicle.  The benefit of lowering the vehicle with the coilover shock body vs spring compression is that you do not lose suspension travel and do not force your vehicle to have a worse ride because you adjusted your coilovers very low.  Redline360 is an authorized BC Racing dealer.  BC Racing honors your warranty when purchasing your BC Racing Coilovers from Redline360.

TEIN Coilovers Honda Prelude (1992-2001) Street Basis Z / Advance Z / Flex Z

TEIN Coilovers Honda Prelude (1992-2001) Street Basis Z / Advance Z / Flex Z

Fitment Information Honda Prelude (1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001) Select kit type option in drop down before ordering Specs & Features Note: Image is only a representation of the coilovers.  TEIN doesn't have vehicle specific images.  Your coilover will be specific to your vehicle.  All kits are sold in a set of 4 coilovers & are genuine Tein backed by a 12 month warranty Street Basis Z ( GSH92-8USS2): 1992-1996 Prelude: Front Drop: 1" - 4.1", Rear Drop: 1" - 3.8" 1997-2001 Prelude: Front Drop: 0.9" - 4.0", Rear Drop: 0.7" - 3.6" Spring Rates: 560 lb front and 224 lb rear Requires the reuse of OEM upper mounts Fixed Damper Settings (non adjustable) Street Advance Z ( GSH92-9USS2): 1992-1996 Prelude: Front Drop: 1" - 4.1", Rear Drop: 1" - 3.8" 1997-2001 Prelude: Front Drop: 0.9" - 4.0", Rear Drop: 0.7" - 3.6" Spring Rates: 560 lb front and 224 lb rear Requires the reuse of OEM upper mounts 16 way adjustable damper settings Flex Z (VSH92-C1SA3): 1992-1996 Prelude: Front Drop: 0.1" - 3.9", Rear Drop: 0.8" - 5.9" 1997-2001 Prelude: Front Drop: 0.3" - 4.3", Rear Drop: 0.4" - 6.3" Spring Rates: 560 lb front and 336 lb rear Includes front camber adjustable & standard rear upper mounts 16 way adjustable damper settings Product Description Street Basis Z: Street Basis Z is strictly a ride height adjustable kit. This makes it a perfect setup for the daily driver looking for an increase in handling performance without compromising comfort for everyday use. For many of you considering a lowering spring + performance shock absorber combination, the STREET BASIS Z makes even more sense as we select appropriate spring rates and valve our dampers to match. No guesswork on the end-users part in trying to match one brand of springs to another brand of shock absorbers. The added height adjustment feature allows the end-user the ability to adjust ride height to their preference, something that lowering springs lack. Being that most vehicles are slightly unbalanced from left to right sides, that means you can easily adjust the ride height so that each corner is even from their opposing sides.  TEIN Street Basis Z Coilovers are TEIN's entry level coilover that gives you all of the benefits of a high quality height adjustable coilover at an entry level price.  Street Advance Z: TEIN Street Advance Z coilovers are designed for those who want more performance from their coilover system.  Designed to provide a stiffer yet comfortable ride and aggressive stance, the street advance coilovers have 16 way adjustable settings giving you a much more noticeable feel in damping force change.  These coilovers provide plenty of shock travel even lower than standard vehicle ride height.  These coilovers adjust via an ultra strong ZT coated threaded sleeve and have updated internal components as well as external coating to dramatically increase durability and product life.  Excellent choice for daily driving, and great for weekend track use. Flex Z: TEIN Flex Z Coilovers are the latest in TEIN's generation of high end coilovers.  The difference with Flex Z is that you are getting a coilover that would normally cost almost double the price.  The new manufacturing systems that TEIN has put in place with this line of coilovers has allowed for them to produce these coilovers at a lower price and pass that savings on to you.  Quality and performance remains top of it's class and TEIN builds these Flex Z coilovers with the highest quality standards. TEIN Flex Z has an awesome twin tube internal system that gives you one of the best street rides we've seen.  In addition, the full length height adjustment system enables you to lower the car to the max allowable level and still maintain the same shock travel and ride quality.  TEIN Flex Z is 16 way dampening adjustable (compression and rebound together) so you can made the ride stiffer or softer depending on what you are looking to achieve.  For example, you can set the dampening to a low setting for when you are daily driving the car and set it up to a stiffer/firmer setting for track or competition use.  These coilovers include upper mounts for each installation.  Each kit comes with either reinforced rubber upper mount or a pillowball upper mount.  Pillow ball upper mounts are for strut suspensions and include front camber adjustment.   Includes a one year limited warranty from TEIN when purchased through an authorized dealer such as Redline360
