I asked him if these were issues on vechles that come already equipped with F-Sport parts from the factory and he said no. He's always been honest with me and the dealership is really good with installing aftermarket enhancements for owners but he really felt strongly about going F-Sport on the suspension if the vehicles don't come from the factory with them pre-installed.

I'm not looking to drop the car super low and only want the gap reduced a bit. I want to maintain the smooth ride I'm used to but could tolerate something a little stiffer too. Are issues common with the F-Sport suspension when they are added after delivery?
What?

Okay first thing's first....F-Sport model =/= F-Sport accessories. No F-Sport 2IS models come factory installed with the F-Sport accessories springs and shocks (or any other F-Sport part for that matter).

Second, alignment......camber is already negative from factory. Get an alignment after you lower, get front toe both to 0, and rear toe to 0.10. With the drop of the F-Sport, you will get roughly -1 to -1.5 camber all around (after alignment)

Tire wear....get the Figs bushing....most tire wear issues are induced by improper toe specs, and the car is designed to go toe-in when you brake while turning. Braking = tire wear, toe in = tire wear, toe in while braking = more tire wear.

I must be the only member who has stated this to date, but the FIGS bushings made my car ride harsher than any car I have ever owned, worse than a civic with ricer APR coilovers, yes I did just go there lol, literally unreal, so bad that I actually sold the FIGS.

And this was on luxury pacake suspension
