Fitted these too my 06 sc about 3 months ago. Of all the mods I've done on all my cars in the past, this is one of the best modifications I've done. Feels much more upto date just by flicking the paddle and up shifting. Last night the range had the trailer and a friends Renault traffic that's loaded with his mechanic workshop on the back. Friend who I was helping said even with that weight the gearbox and paddle shifter is so smooth.
One downside tho, it make you wanna red line the car and makes it feel more sporty so tend too find the petrol mpg worsens when your using the paddles hahha
