Bigger isn't always better......!

 

LOL. Is when you're trying to prevent dirt from flying all under the front of your car!

 

Ok, I eagerly await your multi-product test based evidence to back up why size matters... and why your extra inch makes my flap insufficient at its primary task.

 

 

Don't need to do multi-product testing,
Quoted from the MSA 2013 rules:

48.1.12. The fitting of mud flaps of a flexible material of 4mm minimum thickness behind each wheel extending to a minimum of 40mm each side of the tyre tread and to within 80mm of the ground when the car is unoccupied is mandatory.

 

They look great Tim, on closer inspection of mine they are cracking also, so replacing them just in time.

The 4mm will be hugely better....looking forward to receiving my box of goodies soon.

 

Don't know if I'm being thick, but how can some mudflaps be £600 seems overly excessive. I can see how some are £30ish cheapys, then the cheaper Scoobyworld/Rallytech at about £60-£70 and their better ones around £100, but to jump from that price band to £600?!?! (and I can think of a lot of other things I could do to the car with £600, before flaps).

 

pleased with my performance creations at £65
