Herzel... maybe your right foot is NOT the...
only thing that is old.
I find the STOCK brakes are more than adequate for these cars especially as cruisers and ESPECIALLY for the way I know you drive.
I suspect that maybe a fresh set of rotors and pads... along with cleaning things up a bit and INSURING the calipers SLIDE easily on their mounts would do wonders for your ride... even if they are not worn out!
Spend a $100 bucks doing that first before you spend $$$$ on a brake kit, tires and wheels like this one here from Allison Automotive:
Fiat/Bertone X1/9 Big Brake Kit
You are buying a Big Brake Conversion Kit for the Fiat or Bertone X1/9. This kit is used to install the front brakes from a new Fiat 500 onto the X1/9. The kit includes everything needed for the conversion. The kit includes Wilwood black coated calipers and brackets, performance disc pads, braided steel hoses, new rotors, new steel caliper adapters and grade 8 hardware. The original front brakes are 9" non-vented rotors, this kit improves the front brakes to 10.25" vented rotors. The braking improvement is amazing! This kit makes your X1/9 stop like a modern sports car. Braking distance is shortened by 25%! Replacement parts are readily available since the kit uses parts for the new Fiat 500. The calipers are 4 piston WILWOOD units with autocross and track day performance disc pads.
The kit has two options: either DL10 or DL20 disc pads. The DL10 are street pads, the DL20 are performance street and autocross pads. Both kits are the same price.
NOTE: This brake kit requires 15" or larger wheels.
The kit includes:
2 Wilwood black coated calipers
2 caliper brackets
DL10 Street pads or DL20 performance pads
2 Braided steel hoses
10.25" vented rotors
Grade 8 mounting hardware
