Very easy substitution. Visibility is even more enhanced by installing a Goodyear Wide Angle 17IN rear VIEW MIRROR that clips on perfectly over the factory mirror. 2 Thumbs Up!!!

+3" Risers are installed on the stock CS wing. Noting:

• Risers appear to be well designed and manufactured. Do not expect any stability or strength issues.
• Install - use the stock / oem mounting brackets, not those included with the kit as those are intended for the SilverRocket wing.
• Was successful in maintaining the same wing angle (2.1 deg.).
• Visibility through the stock rear view mirror is much improved and now only limited by the roll cage and roll bar padding.
• Possibility of increase of rear downforce is not yet known. I have an event later this month at Road America (first time), which should show if there is enough of an increase to result in a potential downforce unbalance between the front and rear. Will also compare at known tracks later this year (Road Atlanta, Sebring, etc.) to better know if any other impacts (top speed, etc.)

Overall, am pleased with the product and installation results at this point.

Buy with confidence from Kimbeli. True Professional.
I recently bought 2 x GT4 RS Clubsport and both ran with extended uprights in their series.
Mainly for better rear vision, with the extra benefit of more downforce.
