After driving the R34 a lot on several tracks, including a home-made track, I think I can give a little review on it.
The car's braking is great, it feels stable even under emergency braking. However, there seems to be a specific amount of throttle or brake input that will simply cause a whole lot of understeer when the front wheels aren't pointed straight. So I found a relatively cheap cure: the grass. The induced oversteer helps the car turn very well. Downside... tire wear... It's manageable though.
The very first thing I noticed when driving it was the gearing. Especially useful on slower tracks/tracks with slow corners are the first 3 gears. Perfect for accelerating out right when the engine hits peak torque. Then the gears shorten from 4th to 6th to provide more use of the powerband at high gears. So that I liked.
At first, I felt as if the car understeered for no reason at all. But then I realized I was too used to driving on Race Softs... This car still wouldn't accept trail braking though. I like how max power wasn't the aim for this tune though, it kind of says true aftermarket tuner, not crazy nut job.
So, I decided to actually hot lap a bit. In Tsukuba, I got a 58.278 without changing a single thing from the original tune. It's a fast car, no doubt. Good job.
Edit: Damn, I just read through the post and realized how messy it is. Certain aspects here and there mixed together.
