Are there any?

Just looking at the price differences between the two ranges for 380mmm brakes...

 

most of the suspension , wishbones etc, same as s type/xf and xj etc
so id assume you could fit upgrades from f type with minimal mods

 

How about the 5.0 engine?

 

engine is the same. And I wonder where they got the 550 HP F-Type R engine.... maybe... the XKR-S tune?!?! Im sure there are some tweaks but who knows what they re-use. Its a small company that makes the sexiest cars ever to grace the planet.. they got to share alot of parts to keep costs down.

 

all the 5.0 litre xk / f type engines are same ,they may have different bolt ons to aid fitment but its the different maps that they use that alters the power output
I was in talks with a factory tech and apparently there is a 600+bhp map in there somewhere
now to get it unlocked
