I'll try to be a little more constructive with my response to you lol!

To be honest unless your a top flight driver I'm sure you won't be able to tell the difference on track

The STD kit items are just fine and have a little more flex so generate a bit more grip and are more resilliant in crash.

I have heard some B44.1 owners running the FT graphite rear arms as the standard kit ones flex a bit causing the driveshaft to pop out of the diff outdrive.

When you break a part just stick on a STD part as they are cheaper and should
hold up to a bit more punishment

As for chassis, the team tend to use the kit plastic item over the FT item

HTH
