i had autobahn first,
and now i have the golpher as i needed a slightly slimmer rad the autobahn was 40mm thick, the golpher is 26mm.
the golpher core is the same thickness as a stock glanza but a heck of a lot cheaper to buy.
the golpher is also over half the weight of the autobahn one, and the qaulity is better than the autobahn one aswell
