On facelifted GS, apart from the grill design, and staggered wheels on the F Sport compared to the square wheel setup on Sports Luxury is there anything else that are different?
More adjustability on the seats on the Sports Luxury?
Rim designs are different.
Not sure if there come with LSD and non LSD?
Are the F sport springs lower than the Sports luxury?
Steering wheel are different, full leather vs a mixed of wood and leather.

Are the F Sport grill easily interchangeable with the Sports Luxury?

 

RWD F-Sports will have bigger front brakes, staggered wheels/tire as you mentioned. Wheel designs are also different between F-Sport and Luxury package.

F Sport models have the different interior treatments: digital instrument cluster, F-sport seats/mats/steering wheel/Aluminum Trim/Black Headliner/Aluminum Pedals. LSD and Rear steering are optional features.

The Luxury package will have more seat adjustments, semi-aniline leather, wood/leather steering wheel, AFS, rear door shades, rear seat climate controls and probably a few other niceties i've missed...

The F Sport springs are not lower from the factory - but the AVS is always actively adjusting so the ride is not as compliant as the Lux AVS which maintains a single dampening throughout.

A few folks have done the swap of the base grill to the F-Sport grill (requires bumper removal and possibly a smaller washer reservoir):

Thanks @AJLex19 . The horizontal grill on the Sports Luxury looks a little busy for me, hence the question about the grill.

At least the grill is easily interchangeable.

For future reference.Parts needed :

Right brake cooling duct (optional) : 52811-30020

 

@AJLex19 F Sport bigger brakes? Do you mean larger brake disk or different calipers? On mine the sports Luxury front has I think 4 pistons calipers (I will know for sure when I bleed the brakes this weekend)?

 

​​​​​​You're correct on the 4 piston calipers.

RWD F sports have two piece 14" rotors (13.1" rotor diameter on non rwd f sport models).

 

The luxury spec also has 4 pot fronts but to me they just differ by design. The disc are single piece on the lux package and 2 piece on the F Sports. I didnt get to measure the size of the F Sport though.....maybe same diameter as well? Anyway i changed mine to the GSF 6pot and larger disc for about a year now.

 

The Sports Luxury isn't a trim we get here in the US so it's hard for some of us to answer.

 

Definitely 4 pistons front with one piece rotors.

Ignore the cheap Chinese tyres, they are dangerous and not responsive in the dry at all. I don't want to even try them in the wet. I'm ditching them this weekend.
