I've read most use 20mm spacers on the fronts and 15mm on the rear. Would that also work with the 20" Senta wheels?

 

I have that setup on my 08 XKR . works fine.

what year ??

 

Spacers will not work with Vulcan rims without modifying the wheels as they have no reliefs for the wheel studs. I would check to see if your rims have before ordering the spacers.

 

I think you’ll find that you need to trim the non-threaded part of the rear wheel studs off to prevent them hitting the back side of the wheel when using the 15mm spacers.
That’s what I found when trying to add them to my 2007 XK with Senta’s (haven’t had time to do that, so no spacers on my car yet).

 

Trimmed of the rear wheel studs and I'm happy! 25mm lowering springs are bought and will put them on the car during the winter.

Before.....





After....

 

Wow, is it just me?
The rear no longer looks flared.

 

Like wise here. I cut the tips of the wheel lugs with a mini grinder and all fit nicely.

 

I initially thought the same thing. Camera angle? The flare is still pronounced Peter's second pic.

 

I wish he would take the identical picture to the one before the spacers.

There is a lot of precedence for this in design. And a ton of work goes in 'behind the curtains' to create certain illusions and associations. I am wondering if this was deliberate to give it a muscular rear and the association to the E-type that shared the same unusual proportions.

(they make the castles at disneyland look bigger by planting disproportionately smaller things next to it.)

 

Even with the wheel studs cut down, 15mm spacers will not fit with Vulcan rims. 20mm might just fit. Problem is, when you bolt the spacers to the vehicle, the lug nuts that attach the spacer to the hub stick out higher than the spacer face (wheel mounting flange of the spacer) and the rims will not seat properly. Most rims have releif's cast into them in this area, but Vulcan rims don't, they are flat. Only way to make them work would be to mill out relif's in this area.

 

SORRY. I remember now , Its been 3 yr,s. I had to cut off a few mm.
