pcgoodie Posted June 23, 2018 Share Posted June 23, 2018 hey all!... I put locking wheelnuts on the seven this weekend, and it has effectivity thrown the wheels on each corner or of balance, with the a really pronounced shake on the steering at 70mph.Don't really want to start a thread about the usefulness of locking nuts, but rather, does anyone know a good way of weighting the other three nuts so I can make the 300 miles back to my normal nuts without shaking my teeth out of my bonce?!!

pcgoodie Posted June 23, 2018 Author Share Posted June 23, 2018 Any advances on JK's "get me home" fix it I did want to keep the locking wheelnuts on longer term? Link to comment Share on other sites More sharing options...
SM25T Posted June 23, 2018 Share Posted June 23, 2018 Unless they are monsters, they shouldn't have a big effect at that small radius. Are you sure it is these nuts ? Tyre fitters can have problems balancing wheel/tyre at the low pressures we run at ... tyre flexing or moving on the rim at 18psi. I have to get them to balance at 32psi ... then reduce the pressure afterwards. Link to comment Share on other sites More sharing options...
pcgoodie Posted June 23, 2018 Author Share Posted June 23, 2018 Yeah... Seems that the nuts are the only variable, as I've been driving on them all week without problem before fitting them last night... Clearly I've never experienced such issues on heavier cars, but 13" wheels make the difference more material I guess... The lockers are twice the weight of the other three nuts Link to comment Share on other sites More sharing options...
SM25T Posted June 23, 2018 Share Posted June 23, 2018 Time to take them off then. Link to comment Share on other sites More sharing options...
ScottR400D Posted June 23, 2018 Share Posted June 23, 2018 JK’s idea of putting all the locking nuts on one rim is a good one, or perhaps two on each rear rim, opposite each other. Assuming they do locate correctly and it’s the mass that’s causing the issue and not something else. At least you’ll confirm that’s why you have an issue quite quickly.

prangerman Posted June 24, 2018 Share Posted June 24, 2018 Strange. I have used locking wheel nuts on my Sevens for 12 years without a problem. Tyre fitters do struggle to get the weights in non-fouling positions on the wheels, but a properly set up Seven shouldn't have problems with locking wheel nuts. On the GP circuit at Brands last year, I have no issues at full pelt. My car has been flat floored and laser aligned eye. Peter Link to comment Share on other sites More sharing options...
elie boone Posted June 24, 2018 Share Posted June 24, 2018 Did you try to run without the locking nuts, i.e. with 3 wheel nuts ? it's perfectly safe. did you just changed the wheel nuts or did you got the wheels off, maybe then there is some dirt between the wheel and the hub.

SM25T Posted June 24, 2018 Share Posted June 24, 2018 They must be huge beasties. If you need them ... go for McGard or something that size. Link to comment Share on other sites More sharing options...
A10ROX Posted June 24, 2018 Share Posted June 24, 2018 Has the all on one solved the issue?if not .. are you sure no weights have come loose?Are the tyres new? Spirited driving on new tyres can cause them to move on the rim ...racers tape weights, polishers might record weigh .. with new tyres mark the position of the value on the wall and watch them move ... probably more of a track issue Link to comment Share on other sites More sharing options...
rj Posted June 24, 2018 Share Posted June 24, 2018 Once you've locked the brakes just slightly on a track they're out more than a few grams. When I balance the wheels for the tin top I continue until the machine says "0" on all wheels.Anything less than 8 grams for the Caterham and I don't bother because it'll be out after the first trackday anyway. (And I hardly drive the car on the road because I'd loose my license). Link to comment Share on other sites More sharing options...
