Aftermarket alternatives

[zee]

Being in Canada, there are a few parts we have to source ourselves (FactoryFive has fortunately set up vendors that have packages that give us everything to get to the complete kit, so it's not too bad). However, this also opens up the possibility of getting (potentially better) alternatives.

EDIT: The engine is 347 with a TKX transmission. The rear-end is IRS. Going with 15" wheels.

For the following, those of you who've built before, do you suggest just getting the FactoryFive option or are there better alternatives?

Front Lower Control Arms
Front Spindle Set + hubs
Power Steering Kit

11" Front Brake Kit
Roadster 11.65" IRS Rear Brakes
E-Brake Handle

9.25" 31 Spline Roadster Drive Shaft
2015 IRS Completion Pack
2015 IRS 3.55 Center Section, spindles, hubs

Wilwood Pedal Box and Hardware

Polyurethane Engine/Trans Mounts 302/351
Accelerator Pedal

Fuel Tank Kit (opportunity to get a bigger tank?)

Thanks all
