They use water injection alot on high power cars mate, mostly high power YB Cossies, and I remember at the rolling road day I went to many a year ago Fensport had it on their Corolla
They use them for setting Launch limiter i.e you can have your foot to the floor and it will only rev to say 3.5k which would be ideal revs for a launch They do sound fucking wicked aswell but will fuck your engine up
Idrees has a good point those springs are upside down!! I might be talking shit here but I put money on it sitting lower with the springs on the other way up T1R's wear fast as do parada's but grippy tyres are soft compound = wears quickly
Kawasaki green ftw I ran 50 profiles, 45s looked lost in the arches plus 50s are comfier when riding on coilys Wouldnt go for T1R's again though I found them quite shite tbh Prada spec 2'sd im going to try next
