Hi all

Had a set of JBW minilite's on the Vitesse for several years and very happy with the fit and how well they have stood up to the elements. Fitted M12 studs to Gt6, Vitesse, and the wheels fit with no problems using 60 degree open ended wheel nuts.

Seriously thinking of buying a set of their equivalent 4 spoke revolutions style wheel, Revolite's 6 x 13 for the Gt6. Original 4 spoke Revolutions rarely come up in 3.75/ 95.25mm PCD, and  need sleeved nuts and not sure if the original Revo wheel could accommodate m12 studs on wheels made with the Triumph PCD. 

Also remember reading somewhere that there were some clearance issues with new revolutions fitted to some small chassis Triumphs.

Anyone fitted JBW Revolites to a small chassis Triumph?

I remember comments about Revolutions on the small Triumphs although I can't remember what the clearance issue was, bulkhead or calipers.

However I suspect that the geometry of the old 'genuine' Minilites and Revolutions was slightly different; offset, rim clearance, etc given that they were different manufacturers.

However looking at the JBW website the dimensions for the Minilites and Revolites as identical and given they are the same manufacturer I would be pretty confident if one fits the other will.

I had to look up what wheel 'poke' meant :huh:

I think it was on the top wishbones (of all things). Cured with 5mm spacers.

ET20 when needs to be 16?

Agreed. This is what I have on my GT6 Mk2. The inner edge of the rim is quite square and conflicts the top outer end of the wishbones. I tried relieving the wishbones a tad, but it wasn't enough.

Apparently (?) some cars don't need a spacer!

It's a shame that the Revolutions are nor offered with different ETs. Presumably just the machining of the cast blank.

Is it the genuine Revolutions or the Revolites you have Ian?

The JBW Minilites and Revolites have the same ET. It's the old 'genuine' and unavailable Revolutions that are ET20.

The JBW wheels are ET16. Both types.

Hence my comment that if the JBW Minilites fit then I would expect their Revolites to fit also.

Ok, agreed.

I think there may be some intermediate Revo styles @ ET20, which are neither the true originals (which did fit without spacers) or the current Revolites which should (at ET16) fit without spacers.

Modern reproduction 13 x 5.5" Revolutions from Rimmers or Canleys in 2011.

Fitted with tapered seat nuts on M12 studs. I had sleeve nuts on my previous set of Cobra Superslots and found them a bit of a PITA.

They're very nice. Suit the car.

Agree about the sleeve nuts. Have them for the 15" X 6" on the Scimitar. They are bloody heavy and getting the nut to start on the stud is a real pain.

Revolution still do 13x5.5 for the small chassis cars. But significantly more expensive than the JBW version.

To fair Nick, Revolution like the genuine Minilite used to have what they called road and competition versions of their wheels. The competion wheels supposedly being lighter. As these were apparently still aluminium alloy and not magnesium one can only assume this was achieved by thining down the rim section.

Might be this giving differences in fit.

Thanks all

Revolutions do look good on a gt6. Very Nice looking car. Can't see 4 spoke revo's listed at Rimmer Brothers. Think the Revolite's are a good price.

Their minilite's come in three different offsets ET20 for the 5", ET25 for the 5.5 and ET16 for the 6". The 6" Revolites are ET16. Think i have the 5" on the Vitesse, so ET20 no markings visable on the outside so need to remove a wheel and have s look.

Finally had the hernia op a couple of weeks ago so no jacking up cars at the moment.

Note that unlike offset and set-back, the ET number is influenced by the wheel width. I always need to use an online calculator to figure it out.

FWIW, I do know that ET13 on a 6” rim is pretty much perfect on a Vitesse but a not quite enough on the front of a square tail GT6 or Spitfire.

Wise decision.

But of course :huh:

I got it wrong, what I thought were ET figures on the wheel specs are actually listed as offset sizes, I thought they were the same thing.

As in, the distance in mm (+ or -) from the centreline of the wheel, irrespective of actual wheel width, correct?

I regularly struggle with this concept and corroboration would be much appreciated  :wallbash:

Was going to go for Revolite's, then saw an set of 4 old revolutions 5.5 x 13 on ebay. Look straight in the photos will need a repaint and polish. Placed a bid and won for £122.00 Will need wheel nuts. I'll post a pic when they arrive.
