What sort of speeds are we talking about and in what conditions?
The most I've had the supe up to is 130 before I shit myself (and that's on an open motorway, in the dry.)
Around town, the amount of speed bumps, coppers, potholes etc means the most i've ever hit is probably 70-80 (on a carriageway, not through residentials)
Maybe its to do with the power difference, mine is still a stock TT auto? Although for 7 years previously I was driving a 1.4, 75bhp VW Golf but I didn't have a fear of driving the supra, I was used to the power and kick by the the end of my 350 mile drive home from picking her up!
Do you think it's the modifications made to the Supra that instills more confidence? Mine is completely stock (save for a few pipework bits in the bay, UK brakes and new porterfield pads all round) and I would never hammer it in the wet as I don't have confidence in 20 year old suspension parts (even from a well made motor like the supra!)
I will happily admit I drove like an absolute tool for the first 2 years after getting my licence (racing my mates (75bhp vs 105bhp), going round a roundabout the wrong way just to win etc (I said I was a tool!! ) so I consider myself lucky not to have been killed/killed someone/seriously injured and thats just in a slow mk4 golf! Once I realised I didn't want points on my licence (and never have done, thankfully!) my driving just changed instantly.
I now feel like I am more patient, calm and measured on the road. The Supra gets the odd blip when its a clear road and the conditions are good but a stock setup feels fragile.
