We did constantly flat 9.0 sec with the M4. Two blokes inside, so he'd do a very highish 8,8 or 8,9 sec on his own. Which is pretty good for a stock M4 and hardly 10k miles on the clock. I consider the M4 (it is a M4 with CS package, not a true M4 CS) a great granturismo car for the autobahn...

Yep. Does what it should and quite reliable too. I had mine for over 4 years without any issues. I have clocked a few cars with it. The fastest so far was a M4 CS from 2020. Lovely engine. The RCZ R did around 14 sec from 100 to 200 kmh.

There is always a layer of oil sitting on the upper parts of the engine. Even if you leave the engine untouched for months (the longest time I not started an engine was over 2 years and after opening the valve cover there was still plenty of oil and lubrication on the parts). Where the...

Fantastic and a rare paint! Cheers to the first buyer for ordering it!

Enjoy your RCZ!! Yep, hardly anybody in Germany knows those cars. Germans call themselves "the car driver nation" but can hardly tell anything about cars beyond the usual german car makers. I once got a speeding ticket stating "as the driver of the car, make Porsche with plates XXXX..." I felt...

There is always a price to be paid, it is either the discs or the pads wearing off quicker. Which is it with the EBC?

After watching few oil analysis tests, the Total Quartz 0W30 and 5W30 oils prove to be a chemically very stable/strong oil over its service intervals. The viscosity in cold and hot stayed within 5% change compared to new during the whole service interval (as suggested by Pug) where other full...

Have you had a chance to verify and compare the results with a tool like the Dragy?

Yep. Don't attempt before swapping those tyres. I never experienced out-of-corner traction problems in dry when rolling on the Michs. Also in wet the PS4s gripped very, very well. Both, in traction and under braking. I kept them on the car down to 0°C outside temp because they performed so...

Sure they are. They are the only insurance between the road and the ditch. On my R I had Goodyears, Pirelli and Michelins only. The Michelin PS4s stood out as exceptional, down to the very 2mm of tread. I wrote an exhaustive review on those (and a comparison to the PS4) here on the forum. But...

Nice write-up. Love to hear about the R being pushed on a spirited drive. Brings back memories... The R is quite well set up from factory. Both on springs and damping. I never felt a need to put her on aftermarket coilovers. Maybe some Öhlins would do the job better, but there are none for this...

That's a cheap and quick fix. Strangely those never went bad on my +200.000km R. Driving fast all the time pays off ;)

Instead of installing calibrated gauges, the police should have purchased few mid 2000s Citröens C4 and C5. Or some Peugeot 508. The speedos in those cars showed the exact GPS speed all the time across full range.

If nothing else changed in your setup, beside swapping the tyres, then those might be the culprit. Maybe they were not put correctly on the rims while swapping for the winter tyres. And balancing them in two different shops does not guarantee they are now balanced. Do you trust those shops they...

As far as I recall the speedo on my R was precisely +4 kmh over true GPS speed all across the range. No matter if 50 or 250 on the speedo, it always was +4 over GPS. This made it easy to fly under radar and still maintain proper pace.

In the VLN they run the engines with bigger blowers (in der VLN sind sie mit grösseren Turbos gefahren).

Sweet. 300 hp seems to be the safe max level you can put on those engines. There were few RCZ running on that power in the german VLN racing series. Do you have a dragy or similar GPS device to check on 100-200 times your car now does? I wonder if it went below 14 sec.

I personally would not go over 100k km (60-70k miles) with the same filling of gearbox oil. In all of my manual cars I changed it around 100k km, opposite to manufacturer's recommendation to leave it untouched. In all cars the oil was done by that mileage. Burnt and just smelly. After the change...

I think it will take another few years or a decade for some folks to understand and acknowledge the greatness of the RCZ R. Maybe in few years some youtubers will suddenly rediscover this car and spill out some statements about it to bump the awareness. Like they did with many other cars which...

As the old saying goes, keep your hands off the THP 156s. Sad but true. I think you'd have had a different experience in a THP200 or even diesel RCZ.
