Subframe bushes not changed but were checked and are perfect. There's a rear strut brace on it, it's weird I do feel the effect of the rear strut brace but I also feel the rear is light. The rear tyres are 225/45/17 same as what was on the Rotas. Only difference is that I'm running 225/45/17 on the front too rather than the 215/45/17 I had before. I don't think it's an issue with the tyres though. It feels like the rear is either too light or too soft. Is there a place that can weigh the car at all corners do you know?
