It appears to be time to change the shocks (rear for sure - fronts might not need it just yet) I was looking at some of the shock options and as much as I would love some bilstein's or koni's my budget won't allow it right now. I also found Boge, Monroe and KYB. I wondered if anyone has had any experience with these 3 and if they thought any one was better than another. My application will be street for now, but I still want to enjoy the handling strength of the 924. Monroe and KYB are very affordable but I did not know how good they were for our cars.
Any input would be greatly appreciated.
thanks
B

If you don't have the money to buy good shocks, save what you have till you have enough.

Boge/Sachs are OEM, unless you have Factory Optiona/ Konis, or Bilsteins.

Boge Turbo Gas would be my fourth choice, after Bilstein Sport, Bilstein Heavy Duty, then Koni Gas.

After that would be KYB Gas-Adjust, Not KYBs lowest quality non-adjustable products.

Last, and not worth installing would be Gabriel and Monroe.

Somewhere I've seen a quote complimenting Porsche for designing a very good handling car without the necessity to use extremely high spring rates. One benefit of that is the shocks don't HAVE to be super stiff. Recall that shocks are closely related to the vehicle weight and spring rate.

I've not said it this year. If you do a search I'm sure you'll find me repeating myself often. For STREET driving it is almost impossible to safely drive so hard that any decent shock is not adequate. The high end Koni or Bilstein are nice but NOT required. If you do have that kind of cash laying around I do like the Bilsteins. Monroe is, uh, Monroe. I even gave up on the Escalade and put Bilsteins back on in place of the Monroes.

That leaves Boge or KYB. Either one is fine. I even did DE for a long time on the stock suspension using KYB and it worked fine.

I should have said something about Koni Reds.

I would say Bilstein Sport #1. I have Red Konis right now, and they are too soft even for street driving.

Bilstein Heavy Duty is the standard Bilstein, I did not rate them #1 as they are not recommended for a lowered car by the manufacturer.

I guess Koni Sports (Yellow) would be #3

Koni Red would #4 for me. They are too soft for most purposes are far as I am concerned because you have to turn them all the way up so you don't bottom the car in street driving. Might be okay for an earlier car (77), which is much lighter.

this is probably a stupid question, but do you/should you use the same brand front and rear? or are there some interchangeability with brands?

Absolutely use the same.

I'll add my vote to Boge or KYB for the street; KYBs will be cheaper than the former, though. FWIW, I used the Gas-A-Just as gohim mentioned - didn't realize they had cheaper ones.

While you're in there, get new front upper strut mounts, and consider having an alignment done, and also replacing front a-arm bushings. Makes a huge difference to how the car drives - it'll feel all new after all that! Did it to my '82 931, it's lovely on the street, doesn't feel old anymore.

thanks
I was going to start in the rear because I have to do the brakes too - so I thought since the shocks were getting weak it was a good time to do that
when I get to the front - hopefully by spring - I will do like you said and change bushings and check the front brakes. Does it matter where you start - front or rear?

So the kyb gas adjust will be fine for the street? will they be stiff enough?

Are there any bushings that I should check in the rear while I'm there?
Sorry so many little questions - I'm just trying to be as thorough as I can so I can try to do it right once.

thanks

i have koni sports all around, set on medium (2 clicks) and find them to be very well suited to my 931 with stock springs, for both average and more "spirited" driving.

Bilstein gas shocks are perfect for street and mild track days. Have them on two cars.

I have original/unaltered springs and what appears to be a level stance front to rear - I am not trying to skimp on parts just trying to find a reasonable replacement that will maintain the integrity of the 924's handling abilities. kyb and boge seemed reasonable if they will do the job well - right?
thanks

I have been trying to get some shocks (all 4) to replace on my car.
In Oz they are either rare or bloody expensive.

I'd be happy with KYB's as I only use the car for around town.
I've tried ordering thru the US but the freight was dearer than the parts.

Would anyone be willing to purchase and post to me?

part nos for KYB are kg4529 and 363014
I've found some on E-bay but they havent replied about freight.
