Dont get the 3Racing (#CY-31/PU) Alu. Bulkhead Cover (Sport Only) (PP), just get the pro version bulkhead covers and pro version shock towers.
Keep in mind that 3racing aluminium is generally speaking quite soft.
If you fit a spool or oneway to the car i would suggest not using the 3racing universals on the front of the car.
Also if you are running a spool or oneway get a spare spur gear adapter. I had one break at the holes where the pins for the plastic Cyclone S centre pulley go through the shaft.
I personally had some problems with the 3racing bulkheads, there are two versions going around. Others have stated they didnt have the problem but i believe most of those people were running the 3racing aluminium diff bearing holders.
You probably dont need a belt tensioner or the aluminium servo saver.
I have never liked aluminium knuckles or C hubs as i reckon they get bent (but im a pretty ordinary driver
). Whatever you do make sure you replace the stock Cyclone S C hubs, they are made of some really dodgy brittle plastic
(but the rest of the suspension parts, like knuckles, arms and rear hub carriers are made of the normal carbon graphite)
