jammy Posted February 4, 2015 Report Share Posted February 4, 2015 Hey guys been a while since been online but need some help..got this a3 in and its been running 18" wheels with 225/40 tyres on it for months..friday it had new tyres fitted..same size and from other Audi alloys that was on it before. Since fitting tyres the n/s front now sits up against the coilover locking ring and plate..so much so I've had to put 5mm spacer on to bring it out..i know this car and never been crashed and was fine untill tyre change..matching tyres to so I'm out of ideas now Quote Link to comment Share on other sites More sharing options...
Rich Posted February 4, 2015 Report Share Posted February 4, 2015 Ok, where's the real Jammy gone, your post actually makes sense! Good to see you back mate, it's been a while! Could the tyres have a wider rim protector? Quote Link to comment Share on other sites More sharing options...
adam_r Posted February 4, 2015 Report Share Posted February 4, 2015 Hate to say but take 2 wheels off and check they are not staggered... I have seen it before Quote Link to comment Share on other sites More sharing options...
Rich Posted February 4, 2015 Report Share Posted February 4, 2015 That's a point are they all the same offset? Quote Link to comment Share on other sites More sharing options...
jammy Posted February 4, 2015 Author Report Share Posted February 4, 2015 Haha oi ya cheeky git not staggered fitment..these wheels been on the customers car four months with not trouble lol..these tyres came off oem Audi wheels with identical specs and thay didn't rub on the car..the fact its only one side is puzzling Quote Link to comment Share on other sites More sharing options...
adam_r Posted February 4, 2015 Report Share Posted February 4, 2015 I would look for a bent arm or something then. Something is causing unwanted camber at the hub causing the tyre to contact the strut. Really is the only thing that i can think of that would add in so much camber Quote Link to comment Share on other sites More sharing options...
SMARTLY Posted February 4, 2015 Report Share Posted February 4, 2015 Swap wheel and tyres over at the front and see if it changes sides. Quote Link to comment Share on other sites More sharing options...
jammy Posted February 4, 2015 Author Report Share Posted February 4, 2015 Old tyres fone..were scrap..new lower arms balljoints and track rods and ends fitted over last ten days..could be bent hub I guess Quote Link to comment Share on other sites More sharing options...
jammy Posted February 4, 2015 Author Report Share Posted February 4, 2015 Yeah all dame offset mate..both sets of wheels are vag and identical in size specs Quote Link to comment Share on other sites More sharing options...
adam_r Posted February 5, 2015 Report Share Posted February 5, 2015 Lower arm ball joint i think is your culprit here. If this was not installed correctly the hub will sit incorrectly. When you look at the car this one wheel must visibly have a greater camber angle than the one that is not touching? Quote Link to comment Share on other sites More sharing options...
Tony Posted February 5, 2015 Report Share Posted February 5, 2015 Welcome home stranger...... You say it's "sits up against the coilover locking ring" does this mean it's not leaning against the ring..... If it's up against it then the reason is new tyres= more tread hence the reason the old ones didn't rub. If this is the case a change in camber won't help but a change in the aspect ratio will, not good to read after fitting new tyres. Quote Link to comment Share on other sites More sharing options...
jammy Posted February 6, 2015 Author Report Share Posted February 6, 2015 Hey tony hope your well?..whats got me is its only one side?I got customer in and we put the vest of the last four tyres on that wheel and don't touch stall now majority of 8l a3s with 18s are running 215/35/18 so once we have found the problem if any I have advised this tyre size as the way forward..how can I get a good check of the camber? By eye it looks ok,but looks are deceiving,l... I've got rack boots to change tomorro and then its on the ramp for alingment..camber issues should make the laser line sit further cocked then the divers side yes?

Tony Posted February 6, 2015 Report Share Posted February 6, 2015 Well yes if it's a camber issue it will be more negative on the NSF.... It's not adjustable though but you can get a little by moving the subframe. 2006> the castor is adjustable.... If there is a bend we need to identify where so if your having the camber/ geometry measured I/ we need to know what the SAI AKA KPI is?

jammy Posted February 7, 2015 Author Report Share Posted February 7, 2015 So I went and used my mates geometry machine..i was way to excited to remember its name etc spent a good hour checking the car over and making sure all was good.. Being as the car is decked on the ground and rock solid I assume any factory requirments are out the window? I cant upload any attatcments to the thread but a definate verdict of camber issue to the n/s/f its between half and 1 degree negative to the drivers side....the drivers side tire is proper close as it os so any small amount out and the tire was deemed to fail on the coilover....searching around the clubs it appears that setting the toe to 0 is a fav for slammed a3s? And although I have changed wishbones track ends and rods,when on the machine id got both sides al Mio st spot on to 0 further online search found the factory measurements for rod and end as r fitted to the car a nice experience for me if anything and apparently best the car has ever driven since tbay bought it 😇 so I'm going to locate a hub and then problem solved I hope 😃 Quote Link to comment Share on other sites More sharing options...

jammy Posted February 7, 2015 Author Report Share Posted February 7, 2015 As a extra measure I'm going to check the coilover and rotate it 180 degrees in the hub and then try the wheel back on. Worth a shot as a final check Quote Link to comment Share on other sites More sharing options...
Tony Posted February 8, 2015 Report Share Posted February 8, 2015 I'm not going to state the obvious but i assume both front coilover perches are at the same height? Quote Link to comment Share on other sites More sharing options...
jammy Posted February 8, 2015 Author Report Share Posted February 8, 2015 Thay ere indeed mate its been on full drop and never touched stall.plus spent ages getting it sat level a few weeks ago when the rear adjuster plates turned up..

Tony Posted February 8, 2015 Report Share Posted February 8, 2015 Can i ask does the car pull at all and when you corner left/ right is the steering return the same or better one way than the other. Quote Link to comment Share on other sites More sharing options...
jammy Posted February 8, 2015 Author Report Share Posted February 8, 2015 No pulling mate,it did always pull when the car was bought,esp light was on and had a fault within the n\s front. This was for over a year before thay got car.during a major down poor here one of the owner got bit of a spin goin on a drain and the car made a sorta noise you get from tc when it kicks in and the light went off and car stopped pulling left..hub got hot?warped it like it done to my mondeo on the rear that time?

Tony Posted February 9, 2015 Report Share Posted February 9, 2015 For a slammed car the numbers look fine to me other than the additional -30' on the NSF camber. Given the opportunity i would move the chassis by a few mm. Quote Link to comment Share on other sites More sharing options...
jammy Posted February 9, 2015 Author Report Share Posted February 9, 2015 😊 not nad then seeing as its the first time I have used such equipment for alignment 😊 followed instructions and went on instinct from there..is the chassis easy to move?any alignment pins needed?

jammy Posted February 9, 2015 Author Report Share Posted February 9, 2015 I have watched you when you did the mondeo and astra each time so must of took something in 😄 1 Quote Link to comment Share on other sites More sharing options...
Tony Posted February 10, 2015 Report Share Posted February 10, 2015 No you don't need pins, all you need to do is watch the live camber readings while moving the subframe. Quote Link to comment Share on other sites More sharing options...
