Their rebuild kit is actually cheaper: https://germanautosolutions.com/stor...d-upgrade-kit/Quote:

Yup. The G.A.S. one.Quote:

Main reason why i changed my AC Schnitzer Type 3 was that the rim itself is very soft and any uneven surface or ditch would mess the rim and i had to straighten it everytime, also at high speeds the steering wheels would wobble, providing that i used 15mm spacers, AC center plastic caps it was a nightmare and i decided i had enough :D also the ACs were all the same specs 8.5J ET43 these are not.
I will be selling my ACs, also great news is that the seller had coilovers too and i bought in a bargain price, 150$ :D which a steal deal.
Coilovers: Tein Street Advance Z height adjustment also stifness and smoothness, its dope. Condition 9/10

====================UPDATE=======================
Greetings,
As you know my engine had CO at the weekend i went to my mechanic and disassembled the engine, turns out the head bolts (3-4 bolts) were not tightened at the right torque :| so the head wasn't pressed against the block thus the head gasket leaked in three cylinders.

What is more frustrating is that the head bolts were all streched and one of them broke into half. Whoever rebuilt the engine before me should have changed the bolts with new ones. First i took the head at the shop to test for micro cracks, the head was fine and regrinded it to even the surface, 0.06mm was the grind. I bought Victor Reinz Head gasket, Victor Reinz Head cover gasket and Victor Reinz head cover bolt washers.

The oil filter housing leaked so i changed the gasket with Erling OEM. I also changed the head valve seals with OEM Erling.

Also the vanos ignition wasn't adjusted properly and we did that too. After we reassebmled the engine the car started fine, the ignition did its job the idle was perfect. I took it for a spin and the hoses are no longer under pressure when racing, no water leaks everything's like its supposed to be.
I'll take a break and i'll visit the dyno to check the AFR and HP/Torque curves. And at the end a rare information about ZHP Cams :D
Every other person comments different specs for ZHP Cams. I measured with electric measurement tool that turners use, it reads microns too.
The specs are as follow:
Intake Cam Lift: 10.0mm
Exhaust Cam Lift: 9.2mm
Yeap they differ from standard 3.0 (9.7-9.0). That's the info that is 100% tested, I also measured the M54B30 standard cams to check if the measuring tool was reading correct and it showed INTAKE 9.7MM & EXHAUST 9.0, so the results for ZHP cams are correct.
Wow what an update!
1. The new wheels look great! I forgot how clean the silvergray sedan is
2. You didn't list it, but you used new head bolts this time, right? You're spot on that they should be replaced with any rebuild since they're torque to yield (permanently stretched)
3. I cannot believe you used those swiss cheese cams but the more I think about it I guess it really would function ok, just cause more wear on the followers with the uneven surface grinding against it.
4. How did you notice the pressure on the coolant hoses? Did you see water blowing out of the expansion tank cap or something?
5. Nice job on the measurements on the cams! Good that you could anchor your numbers by measuring the base m54b30 cam.
Good stuff. Did you have any headwork done while it was off?

3. I didn't use grinded cams (swiss ones) and reinstalled the zhps as it turned out the lift was bigger then m54b30s
4. After i raced some cars the coolant hose was so hard you would believe it was about to explode, also after i changed my rev limit from 6800 to 7000 rpm the car started blowing water from the radiator cap, as the compression was higher at high rpms more gasses travelled in the water system. But i also went and measured CO level in water system to 100% make sure it head gasket problems, the CO level was way too high.
The previous owner has done head porting.Quote:
