Yea, we looked at making it bigger but it would involve a custom insert which makes it pretty much cost prohibitive.
Turn around will vary depending on how much regular seat work we have. This one took about 6 weeks but we were very busy with our normal stock redone seats. We also did a backrest for this seat too. It's going on an 05 and should look awesome on there. Yes, it comes in any color you want - LOL. I had even thought about doing a rasied logo on it too. I've got some pics of a new way to put the "Vmax" logo on to the middle for a guy we did a few weeks ago. He's got pics posted on the tech or chat site I think. It's also an 05.
Price on something like this is going to run about $350 plus your core. It's much more labor intensive then the stock seat is but is about the best thing for a passenger to have. I do actually have 2 corbin cores (no backrests) I can work with that can be purchased outright too if needed.
