Ian Vincent Posted June 4, 2022 Report Share Posted June 4, 2022 I know that this is a much discussed topic but I have uneven tyre wear on my TR3a. I have seen various posts recommending somewhere between 0 and 1/2 degree toe-in for a R&P set up but is that across the car or each wheel? Rgds Ian Quote Link to post Share on other sites
Drewmotty Posted June 4, 2022 Report Share Posted June 4, 2022 I set mine with. Trakrite as close as possible to zero but ensuring that whatever discrepancy is present is definitely toe in. Quote Link to post Share on other sites
John Morrison Posted June 4, 2022 Report Share Posted June 4, 2022 That is 100% correct. John. Quote Link to post Share on other sites
Motorsport Mickey Posted June 4, 2022 Report Share Posted June 4, 2022 Only a starting point Ian but it's across the car and then change the toe in to suit what you want. More toe gives more understeer. Mick Richards Quote Link to post Share on other sites
John McCormack Posted June 5, 2022 Report Share Posted June 5, 2022 There are some very experienced sidescreen drivers who reckon 1 degree toe out improves the steering markedly. Quote Link to post Share on other sites
Drewmotty Posted June 5, 2022 Report Share Posted June 5, 2022 Any degree of toe out makes my car wander on a straight road. Quote Link to post Share on other sites
Hamish Posted June 5, 2022 Report Share Posted June 5, 2022 I am no expert by any imagination but I did spend quite a lot of time and where possible cheap option fixes to get my car to handle better before I had more power. That seems to still work now I have a little bit more power. I still have the steering box too. I run the tyres parallel. 7/8 front ARB ( spitfire),stiffer front springs, 4a castor and some camber with second hand CR6zz 70 profile tyres to enable over 100mph speeds. aintree is the fastest track I go to with a couple straights over 100mph and some faster corners with a big bump going into beachers but I don’t consider this bump steer, the surface is old and bumpy so more “road” like. Have a look - it doesn’t seem to wander. Quote Link to post Share on other sites

Conversely the toe in gives an understeer which stabilises the direction of the car to run true dead ahead, which is neutralised when the throttle is applied.

John Morrison Posted June 5, 2022 Report Share Posted June 5, 2022 Yes with the penalty of rapid N/S Outer Shoulder tyre wear. John. Quote Link to post Share on other sites
