I will be upgrading the sway bars on my '93 240 wagon soon - putting on sway bars from a turbo - and plan to replace the rear shocks at the same time. I had pretty much decided I wanted to go with the Boge Pro Gas, based on archived postings here and other research.

However, I found a reference that advised that "The Pro Gas shocks should only be used in sets of four (4)" (http://www.rapidparts.com/Pages/vwc018x.html) This poses a problem in that last fall I had my mechanic replace the front struts, and I am pretty sure he put on standard OEM replacement gas shocks, which I understand to be equivalent to the Boge Automatic shocks. The strut inserts are completely hidden and I cannot see the cartridge name.

Will I have problems if I put the Pro Gas shocks on the back and not the front? How about the Boge or Sachs Turbo shocks? (same company - sidebar question: are the Sachs really better than the Boge branded as FCP Groton claims? And how DO you pronounce "Boge"?)

Any help and insight would be appreciated!

ps. - Just read Jessie's post about Bilsteins - I'm open minded on this - would the Bilstein's be better than the Pro Gas? This is actually my wife's car and I want her to be comfortable and feel safe!
