I guess it comes down to how big your wallet is.
1) if you have the stock ohlins then the cheapest route might be a set of adjustable shock brackets with advant-edge motorsports shock extensions. This would easily offset the longer travel rear.
2) For a little more money you could just put in a set of Viper fronts with a set of Maxxperformance shock extensions and you would come out pretty good. I added a set of 02 Viper stock fronts to my srx and I love them so far. Huge improvement over stock.
3) For even more money you could get a set of revalved long travel shocks that could be tuned to your riding style and weight. Many of the performance places such as pioneer or maxx performance many others I'm sure, sell great packages that range in price from moderate pricing to #^%##% they get that much for shocks.
Me I tend to some what of a cheap 'o and opted for good upgrade to viper take offs and spent the money saved on clutching, and this summer upgrade to a nice set of performance ski's.
