I have a 2008 Lotus Elise with just 35,000 miles. I didn't think that it would need new bushings with so few miles, but it turns out it did. I checked the upper wishbone bushings in the rear and they had each started to slide out (you could see about 2mm or so of white plastic protruding (see picture below which is not from my car but looks exactly like the bushing on my car). I purchased the Monoball bushing refresh kit from Inokinetics and had Gator Motorsports (the closest qualified Lotus mechanics to my home) install them. I couldn't believe the difference in the steering feel. It is much, much tighter. One of the better, if not best, modifications I have done, for sure! I encourage others to check their bushings.
