Reply to "Narrowed rear IRS..."

I use 1" narrowed IRS arms on the new speedster chassis, and Kevin from Cool Rides is the one who makes them for us.  He does a nice job on them, but I know cores seem hard to come by lately, so we've been supplying our own and hoarding more for future use.

One note on the discs is that you cannot use the forged caliper bracket with his modifications, you have to use the stamped sheet metal bracket version of the rear disc kit.

We make our own a-arm front suspension, but it is specific to our tube chassis and not suitable for a conversion.
