Kravitz reports that McLaren are only using the integral wheel nut system on the rear tyres, not the front. Interesting.

A case of "if it ain't broke, don't fix it" thinking? Perhaps attributing the problem with their nuts in part to the specific temperature & mechanical stresses that the rear wheels are constantly subjected to over a race?

Could it be a design / lead time on the parts? I'd imagine that such an important part would also need a fair bit of testing before being raced. They've probably concentrated their efforts on the problem end of the car with a view to then update the front as time / resources allow.

That's basically what Ted said the team told him. There had been no problems with the front thus no need to change.

This intergral wheel nut system is still new, the system has to be 100% proved before they can use it on all four wheels. Might be working for others and not mclaren.

The F1 axles I own are: steel for the rear and titanium for the front. Maybe the difference in material is the issue.

Please do not post about general team or race info in here. It will always be moved out to the respective discussion.

Interestingly McLaren used different brake tubs/covers in Monaco. I would think their adjustable system would come in handy around Monaco but after thinking I guess cooling is the main priority.

This week's Autosport Monaco race review mentions a 'piece of electronic trickery on the McLaren, which has been on both cars all year, and Button is now feeling it may be confusing his feel for the car, causing him to make poor set-up choices'.

Any ideas what this piece of electronic trickery could be? Or how it affects things?

Electronic roll control? They use this on their road car.

[westech]

Its called the electronic adjustable roll control.

[GrizzleBoy]

So their anti-roll bars are electronically loosened (word?)/stiffened during cornering?

[Owen.C93]

That would be active suspension though.

Someone with twitter ask scarbs please (if he isn't already reading this!).

Guys we are being out developed!

Q: Autosport magazine has said that Jenson's feel for the car is being "confused" by some "electronic trickery". Any idea what?

A (Craig Scarborough): I don't know, but can only guess it's an engine mapping to replace the fired overrun (hot blown) maps banned for this year.

Q: Guess there's not much else it could be? Any dynamic electronics allowed in terms of steering/braking/suspension these days?

A (Craig Scarborough): No, about the only electronics allowed are in the engine and gearbox.
