Decided to check my wheel bolts with my torque wrench today after doing about 80 miles since fitting my spacers.
I can report that they haven't remotely loosened so I'll call that a job well done
Anyone still undecided on whether to fit wheel spacers or not should just take the plunge asap.
They dramatically improve the look of a GTI/GTD, especially from the rear where most people probably see the car from
Other than the steering initially feeling slightly heavier ( this feeling soon disappears ), there is no downside that I can see up to now
Don't hesitate in buying the 'Sparco' spacers, they really are a cut above in terms of quality and price.
