scrimja Posted January 6, 2012 Report Share Posted January 6, 2012 Why would you suggest it to be dangerous? I don't quite understand why you're finding it so difficult Matt. Is it pedal placement? Difficulty matching the revs? Something else? Link to comment Share on other sites More sharing options...
Phantom Mark Posted January 6, 2012 Report Share Posted January 6, 2012 (edited) There is absolutely no reason in the world to heel and toe on the road, not driving in a manner which Mr Plod would approve in any case, you can write the most convincing essay you want on the matter and it would still boil down to the fact that if your driving your car on the road in a sensible manner none of the benefits of heel and toe would apply on the road, I know because I spent many of my younger years driving like a t**t in rear wheel drive cars and only once I can remember did I lock up the rear end downshifting, 3rd to 2nd in a 2 litre S Capri in the wet entering a bend. FWIW I found all my E46's slightly awkward to heel and toe, the throttle pedal is not so well placed as it was on say compared to my old E34 Sport....

Difficulty matching the revs? Something else? Trying anything youre not sure of involving brakes on the open road could be deemed dangerous.... I had a go and the distance (vertically) between the throttle and brake doesnt suit my technique. I guess the floor mount doesnt help. I think my technique uses the bottom of the throttle pedal and the bottom right of the brake pedal. I cant roll my foot like I used to on previous cars on the BMW. Bit gutted tbh...

I had a drift car with a two way diff. It was always prudent to heel n toe... ESPECIALLY in the wet! Link to comment Share on other sites More sharing options...
momo Posted January 6, 2012 Report Share Posted January 6, 2012 Why would you suggest it to be dangerous? This:- Trying anything youre not sure of involving brakes on the open road could be deemed dangerous.... Also remember, in effect what you're doing is pressing the accelerator while braking. If you accidentally slip off the brake you're going to plow straight into whatever is in front of you. Safest way to learn - book a track day! At least there's less to hit there! lol. However you may find someone there help you learn the technique. Link to comment Share on other sites More sharing options...
Daz 330 Cs Posted January 6, 2012 Report Share Posted January 6, 2012 I wanted to learn in order to take the stress off the m3's chassis. The stress ? Link to comment Share on other sites More sharing options...

Rob- Posted January 6, 2012 Report Share Posted January 6, 2012 Suppose it could be easier on engine, gearbox and diff/subframe mounts. Link to comment Share on other sites More sharing options...

Keith Posted January 7, 2012 Report Share Posted January 7, 2012 (edited) When he says the stress, he means that downshifts at high revs jolt the diff (and I believe Kabir has subframe cracks), due to the differential in wheel speed vs engine speed. in relation to the gearing used. Heel and toeing reduce stress over the entire driveline (especially clutch), as you are reducing that differential and not engine braking to such a degree. SMG boxes do this on downshifts for this reason, amongst others (smoother downshift, increased clutch life, less stress on drivetrain etc).

Matt_S Posted January 7, 2012 Report Share Posted January 7, 2012 LOL. We used to deliberately use this as a technique in drifting. Its called shift locking. Link to comment Share on other sites More sharing options...

Best to select a higher gear then rather than having the rpms all the way round Link to comment Share on other sites More sharing options...
