    Valve grinding

    Theres loads of cars out there with water pumps driven by the cambelt, european cars especially. They changed the impellar to metal a while back, common issue with them. Working on heavies you see the same thing, Volvo FH12's are notorious for the impellar spinning on the shaft but not so much...

    quite right money talks. Its sad when you have to look to the 60's for a companies 'best' times

    Valve grinding

    having done ohh about a billion snapped nelts in my time don't just chuck the valves in and reassemble, lap them in, use only fine paste and not much of it. do it by hand. If worried about reliability some of the ones I have done have gone on another 200k or so miles and been happy enough...

    Caliper placement

    izzmus gen 1 rx7's did indeed have recirc ball steering but they had front mounted calipers, the later gens had rear mounted calipers and track arms that went overt he wishbone to the front of the hub carrier. So again we are waiting for a car with rear calipers and rear track arm mounts.

    Caliper placement

    I concur, pretty much anything new on cars citroen done sometimes well years ago. The first decent fwd car was the Traction Avant, beating the mini by 13 or so years if I recall correctly. Sadly since the PSA group took over Citroen became a shadow of their former selves. They are just Peugeots...

    Understanding Anti Roll Bars

    hes right for a textbook yes, its true the arb increases the outside tyres slip angle thus understeering but I was assuming we are talking real world and not textbook where the rest of the suspension is ignored. Anything with independent front suspension will as the body rolls just reduce the...

    Caliper placement

    Pat I miss read your comment., I thought you were referring to front and rear placement on the front wheels. My apologies. I agree with the rear axles brakes are always cooler than the fronts and the rest of your description. Citroen were using inboards a lot later than 1955's. Also the...

    Understanding Anti Roll Bars

    stiffer bar reducing the roll reduces the camber change of the inside wheel so it has more input on lateral grip. ARB's are only effective when its only 1 side of the car moving like during cornering, the ARB effectively raises the spring rate during cornering. No roll bar cars often lift a...

    Understanding Anti Roll Bars

    Its late so I'm not quite sure what your actually trying to get an answer to. If its ' does a stiffer anti roll bar provide increased cornering force over no/more elastic bar?' then yes a stiffer bar will increase cornering power.

    Caliper placement

    Izzmus what mazda do you have? I have not seen any with the TRE on the same side as the caliper. Pat anyway evidence to back this up? You'd need to do some extensive testing with a moveable caliper to get any worthwhile evidence. Not saying your right or wrong just interested to see if there...
