I always use GG on my cars, so that's everything from the VXR to the MR2 to the 350Z, and have tried the GG on an RX8 too. I had no issues on any of them, and tbh I didn't even realised they did an XL 888. That might be worth a punt, but given that you don't get a huge amount of feel on an 888 compared to, say, an 048, I wonder if the XL might make that worse?
