Did you consider getting the front spoiler ends from the GT4RS as well?

Odds are they will be the same parts as on the upcoming Spyder RS (or whatever they'll call it) but I may want to do the same to my Spyder.

Update: I talked to Suncoast and here is the kit for the front: https://www.suncoastparts.com/produc...Category_Code=

However, it is much cheaper to buy elsewhere, such as my Post #53 with the part#s and diagram.

Why add aero parts to GT4 which are designed for a GT4RS? Could likely have adverse effect. Similar to GTS owners adding the GT4 rear diffuser.

To give it a little different look, the same I guess as it is for any cosmetic item. I do not track my car but regardless I doubt these little items will have any adverse effects.

If you add the front air guides and also the rear wing modification that I have talked about, your car will be balanced. Adding just the front air guides will add a bit more front end grip and can induce some possible oversteer. The side rear mods are mostly for looks and just clean up the rear a bit. Mine are at the dealer. They only become available in right and left this month. Still not sure how to get behind the bumper to drill holes to install them. Appears will have to take the main part of the rear valance off to do so.

Thanks for all the pictures Shawn and 808c2s.

And make it more of a PITA on the RSs to apply PPF behind the rear wheels to keep stuff from being thrown up against the bumper.

@808c2s looks like the center piece is identical minus the 3 predrilled holes. do you mind giving me the measurements from one end as a starting point so I can drill the holes? like the distance from this corner to the first hole.
