On the higher HP kits (3.9 and 5.9) you will need to change the hubs on the car.
All 1988-1991 cars have the same small bearing like the later NON-ABS one (1.495 I.D. bearing) the only time you need to change spindles (and hubs) on this car is if you want the 5.9 axles (use a 90-93 Integra spindle)
The 92-95 Civic had 2 different wheel bearings, a Non-ABS and ABS. We realize you might not be using the ABS system but please check to see if the spindle has the sensor or hole or if it might have been changed to a different one. the non-ABS ones have a bearing I.D. os 1.495 and the ABS style is 1.695. If you need the larger bearings you can use a 94-01 Integra one or the EK 96-00 SI or EX (both have the larger bearing)
On the 1996-2001 civic the difference was designated by body or trim type, CX,DX,HX and LX have the small bearing (1.495)and the EX and SI both have the larger 1.695
All 1994-2001 4 lug Integras ALL have the 1.695 bearings
Is it your responsibility to make sure you order the correct one, custom 5 lug systems can be made for a extra fee (Front hubs only)
