I currently have the GT DD pro 5NM with the official 8nm power supply and the 330mm RS rim and Elite V2 pedals. Overall I am very happy with it (since fixing the drifting axle issue in the early days). I'm still happy with it with the 1.71 update in GT7 which is the only game I use it on for now.
However, now I am retired I might be using the rig even more, I am thinking if getting the ClubSport DD+ as it is currently on sale and selling my GT DD Pro bundle - which appears to fetch around 500-600 on ebay - so let's say I get 450 after a low end sale and fees. I would need a QR2 adapter for my rim, so the new base and adapter would be an additional $450 +/- $50 with taxes and all else considered based on ebay sale.
So the question is, for those that have had the GT DD Pro and upgraded to a DD+, particularly if using a larger 330mm rim, with the current state and firmware and GT7 1.71 Fullforce support is it worth changing out bases for improved FFB fidelity?
Honestly, I find max force of the 8NM wheel to be plenty and I have it tuned down as is. So the gain going to 18nm is all about those subtle peak spikes rather than holding torque. I'm not sure if I would notice the improvement or if I would just be wasting $400-500.
What say you?
