We looked into 2 pot aluminum caliper upgrade for rear brake again and still think it’s not a worthwhile set up for the following reasons:
1. The OE caliper kit by itself is a well designed and high performance kit to match up any from BBK caliper kits and in fact it’s a track worthy set up.
2. The aluminum caliper is a costly item to make, so if we would build a brake kit with aluminum caliper we expect to bring the performance to a higher level with full track duty rotor i.e. two piece rotors with a minimum of 20mm thickness in order to better justify the cost of the kit.
3. Since the rear OE caliper kit is limited to the use of stock rotor thickness (16mm), and it’s not a two-piece rotor so we don’t think the investment on aluminum caliper can justify the performance gain (other than the look).
If you are still interested in upgrading to our 2 pot two piece rotor caliper kit we can credit you $100 toward your new purchase.
Please understand that it's not we couldn't provide this upgrade rather it's because we are a responsible brake company and we want to make sure every purchase our customers made to us is a good and sound investment.
