I need some advice. I am thinking of taking my 2013 GTR to Severn Valley Motorsport to have a transmission cooler fitted as I'm off to Spa in April with Gran Turismo for a couple of days. Last year at Poznan I had problems with the transmission temperature reaching 120 + after just a few laps. I understand its an issue with GTRs. While talking to Severn Valley they strongly recommended getting a new anti-roll bar fitted to help remove the tendency to under steer. Is this worth while getting done? Any comments appreciated.
