I've got a set of 16" 5 spokes with Goodyear Wrangler HP 215/65 tyres, also got a set of 17" Trek wheels which have tyres that are close to needing changed.
Coils/coil packs have a habit of failing/overheating when at the end of their useful life. If the car won't start, I would be looking more towards the fuel pump as yours should have 2 seperate coil packs so theoretically the car should still try to start on 2 cylinders if one of the coils is broken.
Mine has a bit of corrosion appearing but not sure I want it painted all shiny on my 2003 truck, lol.
Mine is attached with P clips, although most are needing replaced now so looking into stainless/galvanised alternatives.
I think the problem is the interval for changing them is so big, people forget to do it. Changed mine a while back and it definately made a difference. It's worth paying the extra and getting the correct platinum spec plugs as well, despite the premium in the price.
My 3dr is exactly the same, already replaced the master/slave cylinder assembly but it made no difference - next thing to change for me is the slave cylinder mounting bracket.
I've been running my 3dr in 2wd for the last 2 weeks as the VCU had tightened up and the bearings had failed and it's not something I would be doing again unless the height of summer. The greasy roads made it wheelspin easily from junctions and it definately didn't inspire any confidence driving...
