Not sure on the the price yet. His shock towers are £30 - £35 each though.
As for the brace, mine fitted fine. I had to fit the brace first and then the steering brace just fitted on the top, flush with the brace. No forcing or anything, it just fit.
They won't be staying on long though. As soon as the new braces become available, I'll be ordering some and dropping a link here 👍
One question, what tooth pinion are you guys running, anyone running a 19t with a 2200kv ?
