powelmac Member 32 Member For: 8y 8m 6d Posted 13/04/18 11:09 PM Share Posted 13/04/18 11:09 PM Having traction issues with my lowered manual F6 ute. Tyres are still 245/35r19, when it wasn't lowered I had better traction as the rear could squat, however now its 50mm lowered with reset herrod leaf springs and an anti-tramp leaf on the top I just can't get traction in 2nd even only on the 98 tune with 327rwkw and new tyres. Does the stiff rear end reduce traction significantly? Might be worth checking out a wider rim/tyre I'm guessing Also broke the water pump pulley last night after being humiliated by a BMWs1000rr Link to comment Share on other sites More sharing options...

If you hit a bump in the road now you have reduced the time & distance you have to work with arresting that energy, therefore you get a firmer or rougher ride. Similarly you are trying to rapidly load the tyre and with the way geometry & physics work, you are loading that axle. Without some of the distance & flex you originally had, the tyre will still only handle so much torque but you are getting to the friction limit of the rubber really quick. You don't reduce the traction so much as make it difficult to feel when you are coming up on that limit. Once you've smashed through the limit of friction to the road it becomes a loosing struggle. Basically if you can get your head around friction, adding more tyre grip will only offer so much. See static & kinetic friction here https://en.wikipedia.org/wiki/Friction#Static_friction Also think about a top fueler, they have no rear suspension and they bring on way more power quicker than you can dream of. But the tyres go through all sorts of crazy deformation. Have a look at the video below about bike frame stiffness, semi relatable? Hope if haven't confused anything for you. In answer to your question, yes a wider stickier tyre may help with more overall grip. However if you think of that graph of friction you potentially still break traction and still loose heaps of grip very quickly. I would lift it and make it a little nicer ride, but that's just me.

As wide as possible helps. If it tramps then get some caltracs or mal woods anti tramp kit. Link to comment Share on other sites More sharing options...

powelmac Member 32 Member For: 8y 8m 6d Posted 18/04/18 07:28 AM Author Share Posted 18/04/18 07:28 AM Thanks @FiftyOne that's some good insight, I guess it's looks vs performance. Im going to try a set of wider rears and see if that works first then I guess I'll need to revise the suspension height if that fails. @camo86TI tried new revalved bilsteins, and different bushes etc which did nothing, half leaf got rid of it 100%, can accelerate and dump the clutch now and just spins compared to a trampoline like motion previously 2 Link to comment Share on other sites More sharing options...

Ford obviously just loved the horse and buggy. Link to comment Share on other sites More sharing options...
