I got excited to finally see a good looking mod of one of my favorite JDM cars, but I was somewhat disappointed. I noticed that the rear wheels have alignment options that shouldn't exist for live axle suspension and I also noticed that the rear suspension gains negative camber under compression, which you should only see on MacPherson strut, double wishbone and similar suspension styles. So I'm a bit confused as to why you made the model look right, but didn't design the physical beams as live axle suspension (You could have based it largely off of the Miramar's race rear suspension just with a few modifications to make it a 4-link coil-spring setup). Also the Silvertop 4AGE had too much low-end torque and the curve was kind of odd and wavy even before 9000 rpm and dropped off badly past about 9000 RPM, then was even more wavy. Dropping off before redline is normal, (depending on the setup) but not to that degree, I never needed to use the last 2000 RPM. And about the Silvertop, if it's based off of the Formula Atlantic engine, it should have only a 16-valve head, make 266 hp and only rev to 10400 RPM if I'm not mistaken, so it shouldn't be a Silvertop. If it's based off of the one Bunta gets for the AE86 in Initial D, It should make good power at the top end up to about 11000 RPM, make about 240 hp and have a 20-valve head (As you made it). Lastly why does a car as light as the time attack Levin put out a bit over 600 hp on 205 mm SPORT tires! It's not hard to drive because it requires skill, I was giving about 75% throttle in fourth gear and the wheels completely broke traction once boost built up, and why on earth does it have drift steering? Anyway, I'll just stop there with the time attack preset, so otherwise I do think this mod looks good, but I really hope you fix these things in the future.
