Too jazzy

I probably can't even tell the difference 10 psi makes in normal driving, but maybe could if pushing on a bit.

I can’t feel a difference, I just set it to the right pressure.

Dave!

Pressures when hot should be far more than 2-3psi higher than cold. But the only time I’ve ever bothered checking pressures when hot was on track days, to make sure they weren’t madly high.

I’m an F1 driver
Can definitely feel if the pressures are a bit off when driving at say 6/10ths or more. It’s surprisingly obvious in the Defender - I have a slow puncture in the rear left, whenever it loses more 4 PSI it feels odd going round right handers.

The Mito I can tell instantly by how harsh it feels - on correct pressures it’s pretty bumpy .

6 series is less affected presumably due to runflats but it’s really obvious is parked outside with one side of the car facing the sun. Hot tires on one side and cool tyres on the other have a 10+ PSI difference which makes it feel really crap.

Feckin awesome drive back from there too - relatively quiet roads and a few sequences of bends where I could really load things up laterally. Yum.

I could feel a pressure difference in the Puma, between a cold 26psi and a (measure hot) 32 psi after a particularly enthusiastic run, but I'm buggered if I can tell a difference in the 330; I'm guessing weight, geo and tyre size play a part. That, and the Puma being really rather sensitive to suspension changes of any kind.

I can tell if the 330's pressures are out by more than 2-3psi. It's very sensitive imo

I drove a E46 330i which had terrible rear diff noise, turned out it had one front wheel fitted on the rear with the directional tread facing the wrong way. Bear in mind these are staggered wheels on the Sports.

Wheels and tyres refitted and it was perfect.

Careful, you don’t want your car sprayed with muck by an angry farmer

I suspect Mik sprays his own muck over it regularly.

Is that the white stuff on the tyres?!

I decided “bright white” was too much, so did them all again in “worn white”.

Changed the pads on the Impreza at the weekend. Wear indicator was making it's presence felt.

No quite so straight forward this time (usual time is around 20 mins per side) as on the drivers side the retaining clip snapped (now temporarily replaced with R-clips until the new stuff arrives) and the reason that the wear indicator was making noise was that one of the 4 pistons was ceased!

So a total removeal of the caliper was needed to get held in the vice to remove the offending piston with big grips and a good clean out was needed. Looks like I have a stainless piston upgrade in place as there was zero corrosion (very common complaint with standard 4 pot WRX calipers) which I was expecting to have to clean up before I replaced the piston, so it just needed a clean up and refit. New fluid and a bleed up and she was good to go.

Will get the clips ordered up today but it's only a 5 min job to swap those even though the R-clips would seem an adequate subsitute.

Carl.

Had a shitty day today so to get myself away from the computer (most of my source of stress) I bought some new cloths and decided to (properly) do the glass and the primary controls on the car.

Fucking hell they were grotty. I ruined at least one cloth just by cleaning the steering wheel. The rest was mostly as expected but the steering wheel was a horrible fucking mess.

I think I might need to get some of those fancy pants microfoam pad things (magic eraser pads?) that basically act like mild sandpaper to do this again then give it a quick rinse off rather than suffering with generic cleaner stuff.

I also need to get some drill brushes and *finally* tackle the roof.

Utterly ignoring work for an hour was quite liberating, too.

Managed to get my car (BMW 125i MSport) serviced and MOT'd yesterday, which it passed, so happy with that. Wasn't cheap though, so will try and look for an indy specialist from next year.

Also paid the balloon payment at the end of May, so been quite an expensive week for me with my car! From what I could tell, it was still worth slightly more than the balloon payment, so thought it was worth doing rather than handing it back - plus I still like the car. Be the first time in maybe 12 years I've not had a monthly bill for a car payment.

The Colin Chapman inspired steering feel of the 2.5 Turbocharged 4WD fastback has changed noticeably in the last few days. Upon a detailed investigation I think a roller or bearing cup had decided to break up resulting in Tiller like steering.



Luckily I overnighted race parts from Japan and now the previously lost deft high speed steering control is back to normal



It went from having very little slop to about 30 degrees of slop in a mile or two. It’s nice and tight now.

Dave!

Mito has developed a hiss which will turn into a hoot if you hold it at part boost as the turbot comes on.

Remains to be seen whether it's a boost leak or the turbo itself on the way out

Struggling to get my head around how that linkage works. I understand the universal joints, but not the shaft in the middle which is usually straight but is bent both ends and has a lump in the middle
