Overall Assessment

Customers praised the product for being well-made, particularly applauding the brackets' quality. Users found the instructions decent and had no clearance issues with bolt heads, highlighting the product's usability. Additionally, they regarded the kit as durable, practical and safe for use. Particularly, in the case of a 64 Chevy Impala, the kit correctly addressed the issue of the car's lowered height, confirming its effective functionality. While some customers had initial troubles with incorrect parts, many were satisfied upon receiving the correct parts. Despite some needing additional instructions, overall customers were pleased with the progress and outcomes they achieved with the kit and would recommend it over competitive products. Some, however, suggested considering a higher-end kit for a less challenging installation.

I was reworking the front disk brakes on a 64 chevy impala convertible... it had been modified with 2 inch lowered spindles and a disk brake kit (not a Speedway product btw) which left the car too low for touring. After multiple costly rim and tire alternative attempts and then trying heaver coil springs to address the lowered height, the car remained a nightmare for driving as the tires inevitably caught the wheel wells on turns... at the most inopportune moment. The provider of the lowered disk brake kit did not offer an adapter bracket for the standard spindles. Speedway did offer these stock spindle brackets, and they work perfectly on the original stock spindles. A note though - the Speedway mounts are built to handle late model mid size GM calipers (mounting bolt pattern of about 5 1/4) not the full size GM calipers (mounting of 7 1/2). The mid size calipers work fantastic btw... but i'd had the full size from the lowering kit... which are now collecting dust on the shelf... oh well!

When first looking at this kit, it looks pretty good. A good intro kit to update your hotrod, low rider etc. But that soon changes, the kit does not have any detailed instruction, so if you are a first timer at upgrading drum brakes to disc brakes, be really for a lot of guess work. My kit was supplied with a few wrong parts that stopped my forward progress. I ended up going to the local parts place to get what was needed to continue. The bracket in the kit seems to be one of the stronger pieces in the kit, but this too could use some fine tuning. You get what you pay for, if I did it over, I would go with a higher end kit.....even with it being more money. It would be worth it...less headaches.. I hope.
