When you click on links to various merchants on this site and make a purchase, this can result in this site earning a commission. Affiliate programs and affiliations include, but are not limited to, the eBay Partner Network.
I'm really not sure if it's available for either, but it shows up in the link. There's no other way to find it that I'm aware of. The GS is the same way, and I've seen confirmation that they have it, just not the F-Sport, which is highlighted as such.
Most likely you will have trouble getting it though, we have been trying to order this in the 4GS section, with no luck. I'm still trying but it says incompatible with my car, but someone has gotten it to work. I'm taking a risk to see if it will most likely you will also be taking a risk as well since they charge even if it doesn't work.
