so after talking to a retailer who sells hawk pads ive learned the HF pads are 4" wide by 1 3/4 tall, and the SI brakes are 5" long by 2" tall.
according to the buybrakes.com website brembo has listed the 88-89 SI/DX as the same rotor, but the 90-91 DX/SI as different part numbers. HF the same from 88-91
HF rotors show as:
Type: Ventilated Disc
Overall Diameter: 231mm
Minimum Thickness: 15mm
Overall Height: 43.8mmFits:
1984 - 1987 HONDA CIVIC HATCHBACK w/ Vented Front Disc
1983 HONDA CIVIC SEDAN
1984 - 1987 HONDA CIVIC SEDAN
1984 - 1987 HONDA CIVIC WAGON / WAGOVAN 4WD
1984 HONDA CRX 1500 DX
1985 - 1987 HONDA CRX DX / SI
1988 - 1989 HONDA CRX HF
1990 - 1991 HONDA CRX HF
2000 - 2002 HONDA INSIGHT
The SI brake rotors show as:
Type: Ventilated Disc
Overall Diameter: 242mm
Minimum Thickness: 17mm
Overall Height: 44mmFits:
1986 - 1989 ACURA INTEGRA
1988 - 1989 HONDA CIVIC HATCHBACK
1988 - 1989 HONDA CIVIC SEDAN
1988 - 1989 HONDA CIVIC WAGON / WAGOVAN
1990 - 1991 HONDA CIVIC WAGON / WAGOVAN 4WD
1988 - 1989 HONDA CRX DX / SI
1990 - 1991 HONDA CRX SI
This is a really hefty difference for me in friction swept surface area as well as just plain overall rotor diameter. I was wondering if anyone has tried swapping HF brakes to SI brakes? I dont want some ungodly huge poorly biased crappy brake setup.
What is needed exactly?
Will it still clear 13" hf wheels?
Do I need the SI caliper bracket or can I use the HF one? This is currently one of the bigger obstacle questions as it doesnt seem I can get my hands on the brackets anywhere.
EDIT: according to hondaautomotiveparts.com, the HF and the SI/DX have the same part # when searching for the knuckle. Great, that means anything that bolts to the SI bolts to the HF. I will edit the thread and post my results as I go, any input from others is appreciated.
im assuming crx's all have 56.1mm center bore
ok so I guess it doesnt matter much if the brackets line up, I just found them at a local junk. They are gonna pull the calipers and brackets then give em to me for 60 bucks shipped. I will install them, and probabbly measure between the 2 and post up whether or not the brackets are the same.
