FTD customs swingarm extensions

[Pandaspeed]

hey new to the forum here.
has anyone heard or used FTD customs extensions?
they make a 7"-12" extension. I was wondering what the maximum you would want to extend your swingarm with bolt ons.
do they damage your swingarm or anything?
im going to be using the busa for a weekend drag bike. work lots in the week so not a lot of street riding. I got the brocks erformance lowering links and straps also.
the reason im wondering about the extensions is im not looking to drop 2 grand on a swing arm and then more for the other parts needed.

thanks for everyones time

Most will say to get an extended arm or weld on extensions. I have no experience with ftd. Good luck! And

For a few hundred $ extra you can get an Evil arm,I know guys with 250+ hp using them at the track with no issues.

You would be better to search all things chrome extensions. I want to say ftd makes them for them or they share the design. They have a very good reputation
