Thanks! I'm happy with the change for sure. Still more tweaking to come!

Just something I learned 40 years ago. I replaced the Boge struts and shocks with gas KYB's. Wanted the stiffer ride so gas made sense. When I tore them down there was oil in the tube. I thought the old shocks were shot and the money spent was well worth it. My 72 T was lowered about 1.5 inches, being a light weight it rode terribly. Pogo and harsh. I talked to a old racer and he informed me that the oil was to dissipate heat from the insert to the shock housing to help the friction heat buildup transfer. Believe about 50 ml any viscosity. He also said majority of people want to use stiffer shocks to increase performance. He said the proper way was to adjust the spring rate for the track condition and shocks for road conditions, bumps, dips, rough and so forth. The shock adjustment was to control the speed of compressing and rebound. However, now we have damping systems like in =my Acura TLX SH AWD A spec that with computers and drive mode selection controls compression and rebound rates

Thx, I'm open to coilovers and they are the natural progression as my driving improves. Right now I'm trying to learn the car without over building it if that makes any sense.

Raising the spindles corrects a bunch of geometry when the car is lowered. Stay tuned.

Great info on the struts. I need to get some 3.5" struts for my build as I want to install "S" model calipers on my '72.... I used to have adjustable koni's on a 944 Turbo. They were adjustable with a white know at the top of the strut, where you did not have to remove them? Too bad you can't get those Koni's to make adjustment easier.

Good plan to use the 3.5" struts. Have you driven a 911 with early S brakes? They are little squishy in my opinion. I believe the yellow Konis are adjustable from the top. Nice feature but more stuff on compression.

Excellent, thanks. I'm working on a lightened C4 Corvette, and I expect to remove about 325 lbs total, including roughly 10 lbs (20%) of wheel and tire weight at each corner. I'm starting with the softer factory 'Base' suspension, but I may find that the car becomes quite stiff and jittery, having lost a bit more than 10% of its total weight along with the reduction in both un-sprung _and_ rotating weight of the wheels. The fresh KYB Gas-A-Adjust dampers currently on it do seem pretty well-judged for the stock setup, so maybe I won't have a problem. But if I do find it too harsh, I want to go with high-quality double-adjustable dampers. It appears that Koni offers only Yellows for my car, and I think those might also be too stiff for my taste. So, I may try QA1's double-adjustable shocks, which are currently $238 per corner. That's enough for me to proceed with caution, but they seem like well-made components. Just thought I'd share that source, in case anyone else is struggling to find a damper solution for an unusual combination.

Thanks for sharing and it sounds like your approach is right. Too stiff on the street can cause erratic handling or serious problems

I think you did the right thing going to softer shocks with no gas pressure. Now do this. I have discovered that a really easy and surprisingly effective way to significantly make the ride better in my cars is to, lower the tire pressure. In my 928 i find 28-30psi works good. in my 1940 Fargo/Canadian Dodge pick up I run 25 front and 22 rear (18 & 20 in. rims, super light truck) This truck was undriveable at 32 psi pressures. Just experiment with your car and see what happens. don't go to low or it won't handle good. I don't really care about tire wear since I only can put 2-3ooo km per year so the tires will last many years even at low pressure. Actually all 4 of my vehicles run on somewhat under inflated tires. When you have terrible roads in your area like me, you need to have a car drive nice or you won't drive it and get that enjoyment out of it; so that's what I have been doing for a few years now and So far it has become a pleasure to drive all of them again. Good luck

This was my fear when spec'ing the suspension for my light-ish weight hot-rod, so thank you for validating my Konis purchase 🙂 ... Like you, I have the RSR bushings up front (in the rear as well, that was quite a job) - but I got the top-adjustable Konis (yellow) and I'm running 21/31 torsion bars (anticipating track usage.) Yes, the instructions for the Konis are like hieroglyphics. Did you put any coolant in the Boge bodies before installing? Anyway, I only got a little bit of seat time in this arrangement before the car went onto a shipping container, but I can tell you it wasn't harsh at all with the dampers set to full soft. I know a lot of guys don't like dampers like this (complaining they never use the adjustment), but having previously had easily adjustable shocks in "fast" daily-driver, I know it is a godsend when you're driving some more sensitive passengers about!

Also, thank you for demonstrating that the Konis don't return. I was not familiar with shocks like that and it gave me a bit of anxiety before installing them, thinking they might be faulty. The yellows (8641-1039Sport & 8210-1159Sport) are super easy to adjust with everything installed - they give you these little removable plastic knobs which you pop on the top and you simply twist them one way or another for firmness. The real test is when my car arrives in 3 months or so (fingers crossed) ... We moved from the relatively smooth roads of Australia to Europe, so we'll see if I made a mistake with my chosen setup!

Professor, you are right on track.. No one wants a race car ride on the street. Hopefully, the spindle relocation will bring the sweet spot for the Koni's. If, I am correct, it will correct bump stop issues from being lower than stock?

Agree, I live in a very urban place that seems to always be under construction or the roads are just worn out! Can't enjoy a car that can't hit bumps. Raised spindles do a lot of things. Like you said, additional suspension travel, but it also helps with bump steer and roll center geometry. You may remember that I modelled the rear suspension in CAD to understand the turbo geometry and how the rear roll center can be adjusted. I added extra camber holes in the chassis. Will do the same analysis for the front. That will help understand the sweet spot that I'm talking about. The shock itself also has a sweet spot. Fun stuff!

Bilstein is always super confusing. On my e46, the HD shocks had the same damping as the Sport, but were made for regular ride height springs whereas the Sport was made for lowered springs. So even in their naming across lines they aren't consistent if the Porsche HD vs Sport are actually different damping.

Man I have not heard such a display of misunderstanding about the how and why of a monotube gas shock function or the effect of the gas pressure in a long time.......the gas pressure chamber is so that there is NO air in the part holding the oil...When any shock/strut compresses there must be provision for the oil displaced by the rod, or shaft coming into the body..Your 40mm inverted Bilstein shaft is 10mm in diameter and approx 160mm long..it displaces that much oil..Many ordinary struts have 18mm or 20mm shafts about 160mm on many cars, 210 on that 88 Volvo a few feet away...The traditional way to allow for displacement of oil was to simply leave a space inside the shock with no oil..shaft comes into body, oil level risies...The valving, a stack of very thin steel shims sitting on the piston at the end of the rod deflect...the damping is an effect of the size and shape of the holes in the piston, the dia and thickness of the steel shims, and the oil viscosity... But conventional non-gas (the mono-tube, floating gas piston nitrogen charged shock was invented by Dr.F DeCarbon and patented in 1949 and Bilstein paid licence to begin manufactur in early 50s..Patent ran out in 1976, May or April...) shock are in essence like a butter churn..Cycle them and the oil aerates..Those holes and shims selected to meter oil at a given viscosity now are metering an emulsion of oil and air..and an emulsion full of air doesn't offer much resistance... Also your inability to compress the Bilstein with your hand and compress the Koni means nothing useful. Shocks move at and have a little more weight and force behind them when mounted on the car...MANY US based "experts" cycle shocks when testing on a machine at a speed of maybe2-3"/s...Bilstein's standard compression and rebound test speed is 0,52 m/s or 20.47 inche/second.. Like the speed in a sharp edged bump or a pot hole. Long in short is the insert is just valve too stiff on compression damping. But I think in time you will find the Konis will also be somewhat harsh on high shaft speed compression damping---like pot holes...Fine on bumps that look like sine-waves. They have been so on the old "Special D" red things from the 60s, for both cars and bikes and same to at least the early 90s when last I mounted some on a Saab 900 16v and was requested to remove them just 3 days later and mount up some second hand Bilsteins....which were fine, and customer once again happy.. Maybe you just got a duff pair.
