Road Racing - Sports Car wheels from Gibson Engineering

  • Precision 3-piece wheels using aircraft grade 2000 series aircraft high strength billet aluminum center


  • True billet center allows virtually any size/width/offset


  • In SAE Cornering Fatigue tests, the wheels exceeded TWICE the required number of cycles


  • Test results show our light weight wheel has extremely high stiffness and strength with excellent durability


  • Perfect for road racing or high-performance street applications




Gibson 18" Road Race/Sports Car wheels lower unsprung/rotating weight over 7 lbs per wheel (over 28 lbs total) while increasing diameter 1" and width 1.5" over stock wheels on Porsche RS America

     
For example, 964 RS America with Gibson 18x9.5 rear (17.2 lbs), 18x7.5 front (15.3 lbs), super light weight 15 spoke design with titanium bolt option



DIRECTIONAL SPOKE DOUBLE-HAT I-BEAM WHEEL

The   LIGHTEST - STRONGEST - SAFEST   wheels ever made

           
Shown in polished finish. Other finishes available on request.

  • All new design perfect for racing and high performance street applications
  • Uses a unique 15 spoke / 30 bolt configuration to optimize strength while minimizing weight
  • Gibson proprietary double-hat I-beam spoke design provides ultra high "area-moment" shape factor
  • Spoke cross-section created with precision custom made CNC side-cutter form tools
  • State of the art MasterCam CAD-CAM produces specialized free-form out-of-plane cutter paths
  • Advanced design and manufacturing technology allow maximum strength at minimum weight


STRAIGHT SPOKE DOUBLE-HAT I-BEAM WHEEL

           

  • Straight spoke version of the original 15 spoke directional wheel
  • Does not require "rights" and "lefts"
  • Same unique 15 spoke / 30 bolt configuration to optimize strength while minimizing weight
  • Gibson proprietary double-hat I-beam spoke design provides ultra high "area-moment"
  • Spoke cross-section created with precision custom made CNC side-cutter form tools
  • State of the art MasterCam CAD-CAM allows free-form out-of-plane cutter paths


ULTIMATE 5-SPOKE WHEEL

The first new design 5-spoke wheel in many years

           

  • Gibson produced the   LIGHTEST - STRONGEST - SAFEST   5-spoke wheel currently available anywhere
  • New proprietary "tri-bolt" 5-spoke configuration minimizes stress concentrations inherent in many other 5-spoke wheels
  • Wheels have no backside bolts or "blind threads" behind spokes
  • Spokes are designed for maximum "area-moment" shape factor providing the most efficent spoke strength to weight possible
  • All spoke cross-sections created with precision custom made aircraft style CNC form tools manufactured in USA
  • State of the art MasterCam CAD-CAM is used "in-house" to produce specialized free-form out-of-plane cutter paths
