Thanks, (Going to Spa tomorrow)
You probably know already, but you absolutely can remove the lower blocks without jacking the car up. You just need the correct tools. You want a T25 for all the pieces at the front (underside blocks or deflectors and vent mesh) and a T27 to adjust the angle of attack on the rear wing. The blocks each have four screw. The vent mesh each have two. You will need a jack to remove the front vent mesh. You do not need to remove the wheels, you just need to turn them to full lock each way while jacked. I know this for sure because I did all of it today at Watkins Glen between track sessions using nothing but the correct Torx heads, a small socket wrench, and a floor jack.

Only .2


For .1RS, if you adjust the rear wing (I think only 3 positions possible), then you should lower the front about 5mm and remove the mesh screens under the fender louvers. For more extreme then add canards on the front.

remove the mesh screens under the fender louvers really help increase downforce?

My understanding is the removal reduces lift (does not increase downforce). Together with rear wing adjustment, overall downforce AND balance is achieved.
Want more downforce? Lower front 5mm, add canards, add 911R rear under-diffuser.

I have an adjustable wing on my GT3 (not RS) that I added. Is this "small block" thing available on the regular GT3? Are there pictures?
