Hi

I will be replacing the struts and shocks on my 84 245 but don't know which to get - Boge Pro Gas or Turbo Gas. What is the difference between the two ? I also plan to replace the 14" steel wheels with 15" turbo wheels and Bridgestone RE 930 tires and install sway bars from a 240 turbo.

I'm not looking for all out performance, just an improvement in ride and handling.Does anyone have experience with either the Pro Gas or Turbo Gas ?

Thanks.

Karl

Hi Karl,

I have used both types of shocks on my 240s. The Turbo Gas is a more

sport type of a shock than the Pro Gas. The pro gas gives a very nice

ride but when the road gets rough and bumpy it stiffens. Also under hard

cornering the shock stiffens. Personally if I had to chose again I would

buy the Turbo Gas because I like the firmer ride and the handling is

more improved with the Turbo Gas. There is more nose dive under hard

braking with the Pro Gas. However, the Pro Gas provides a really nice ride

with a definite handling improvement over stock. Both have a lifetime

warranty, too. Have nice holiday.

Probably everyone one will recommend turbo gas......but I have Pro Gas on my 745 and think they are perfect...I also have IPD bars and Pirelli P6000's.

I have KYB's on my 242 Turbo, and had them on the back of my 244GL.

The Pro Gas is the perfect shock for the rear of a wagon, as they get stiffer as they are loaded. So you get good ride and control when unloaded, but enough damping as you load the car. I have them on the front also but they seem a bit stiff there...

The KYB's did not damp as well as the Volvo Sport shocks i replaced them with.

I think an optimum combo may be Pro gas on the rear, Turbo gas on front....but if that sounds too ridsky I'd recommend Pro gas all around.

BTW...Pro gas will obviously NOT work on lowered cars as they will detect the lowered position as a heavy load and be much too stiff.

I liked the Turbo Gas shocks (on '85 245 DL) with the original springs,

but then I added overload coils in back. The combination is a bit stiff over bumps.

IMHO

Get KYB shocks.

I've had KYB on a '75 245, and an '80 244 later upgraded w/IPD Swaybars. I recently got an '87 245 and put on Boge TurboGas, I regret not sticking w/KYB.

KYB w IPD bars has a much more secure feel, sticks to road around corners, on highway entrances around curves holds at faster speeds.

Karl:

I have this exact set-up on my wife's '90 244 DL; Boge Turbo Gas shocks, sway bars off a turbo sedan, and 15" Virgo wheels (Continental tires instead of Bridgestone, however). The car handles beautifully, however the ride IS a bit harsh. The Pro Gas may be less harsh and give you a better ride than the Turbo Gas, but I have no experience with them.

What size tires do you have? I'm thinking about 205/50/15 for my '87, and I already have IPD sways and will go with boge turbo gas in the near future.

thanks.

I've got some 205-60/15 Continental CH95s on the 6X15X20 Virgo Turbo alloys. The CH95s were on sale ($47 apiece) at TireRack.com and, while they're probably not the ultimate performance tire, seem to do OK. They rated pretty well on Tire Rack's survey, and are decent in the wet, which is an important consideration here in Florida. I'm thinking of trying some Yokohoma Avid H4s on another set of 15" alloys I took off of a 760 turbo; several regulars on this list have highly recommended the Yoko Avids.

I replaced the shocks and struts on my 82 Turbo with the Boge Turbo gas because of an earlier suspension upgrade to my 89 DL. On the 89 I used the Boge Turbo Gas units as well as sway bars from a turbo sedan and a set of 15" Turbo wheels. Greatly improved the handling and they don't produce a harsh ride.

Because of this good experience on the 240's when it was time to replace the shocks and struts on our 740 sedan I went with Boge Turbo Gas. I don't like them on the 740- it produces a much harsher ride than I would prefer.

My parents had an 84 244 and put the Turbo-Gas shocks and struts on it. They are quite a bit stiffer than stock, but were a large improvement in handling. The Pro Gas are supposed to be softer, but still an improvement over stock.
