Coilover Dampers for the Slowtra - The Taiwanese Part 3 (Silver's, DGR and ISC)

Silver's
Silver's is not a jewellery shop but like D2 Race and K-Sport make/sell performance parts including big brake kits and coilover shocks. Silver's was established in 1999 and claim they have extensive R&D for new products and repeatedly conduct street and actual race track tests. There are three coilover shocks in Silver's lineup - Neomax, Litech and the very clearly named 2 Way Racing Suspension. Only the lowest end Neomax is available for the N16 (this unhealthy trend is most demotivating). The Neomax is a monotube damper and feature a 44mm piston (20mm piston shaft) in a 52mm carbon seamless tube coilover body.
  • Part Number: NN101 for N16/B15
  • Damping Adjustable: 24 way single adjustable - probably compression and rebound combined but not specified in website
  • Ride height adjustable: Yes. Independent Ride height adjustable: Yes
  • Rebuildable: Yes but you will have to send back to Silver's in Taiwan
  • Front Spring Rate: 8 kg/mm, Rear Spring Rate: 4 kg/mm.
  • Top Mounts: Not stated in website but there is a mention that pillowball (spherical bearing) top mounts are optional. Apparently the aluminium plate is 7075 which should be stronger than 6061.
  • Other Notable Features: Italian IP F.A 5W suspension fluid with very high viscosity index guarantees efficient shock-absorbing action at any ambient temperature. Am not familiar with the brand hence cannot vouch on its quality. Sorry.
  • Price is not mentioned but probably competitive with BC Racing which to me should be its closest competitor.
DGR
DGR is not to be confused with the Japanese DG-5 and the Taiwanese parent website is only in Chinese at this point. Since I'm hopeless with Chinese the information I have gathered is limited. The website of the distributor in the US is equally dodgy and I've seen more info from eBay sites. You can check it out here. DGR claim many "types" of suspension are available but obviously only the street suspension is available for the N16/B15/G10.
  • Part Number: Not stated. Just look for Sentra N16 or Sentra 180 in Taiwan or Sentra B15 for US markets.
  • Damping Adjustable: 30 way single adjustable - probably compression and rebound combined but not specified in website or at least where I looked.
  • Ride height adjustable: Yes. Independent Ride height adjustable: Yes
  • Rebuildable: Yes but you will have to send back to DGR in Taiwan
  • Front Spring Rate: Not stated, Rear Spring Rate: Not stated.
  • Top Mounts: Not stated in website but probably avail in various types like all the other Taiwanese performance coilover damper brands
  • Other Notable Features: The US distributor apparently offers a lifetime warranty. Please read and understand the fine print though.
  • Price is not mentioned but probably competitive with the other similar Taiwanese brands like D2 and K-Sport.
ISC
ISC stands for I Shih Cheng and is or claims to be a specialized shock absorber manufacturer but their catalogue also show big brake kits and brake rotors. The N1 coilover is available for the Sentra but I could not find much useful information about this model except that it is a monotube coilover damper.
  • Part Number: N003
  • Damping Adjustable: 32 way single adjustable - probably compression and rebound combined but not specified in website or at least where I looked.
  • Ride height adjustable: Yes. Independent Ride height adjustable: Yes
  • Rebuildable: Yes but you will have to send back to ISC in Taiwan
  • Front Spring Rate (Street): 8 kg/mm, Rear Spring Rate: 6 kg/mm.
  • Front Spring Rate (Race & Drift): 10 kg/mm, Rear Spring Rate: 8 kg/mm.
  • Top Mounts: Spherical bearing top mounts are not available from what I see so you'll probably get the garden variety rubber mounts on a 6061 aluminium plate.
  • Other Notable Features: None
  • Price is not mentioned but probably competitive with the other similar Taiwanese brands like D2 and K-Sport.
This is bout it for the Taiwanese. There are more brands out there but they all seem to be of similar technology and are probably from the same manufacturer source(s). Next up will be the Euro big boys..
