What PCD choice
lsdweb - 8/3/12 at 10:17 AM

Hi All

I'm possibly embarking on another project (not bought it or told my wife yet!). It'll be a sprint and hillclimb car. The original wheels are a tad expensive and have a strange PCD, so I'll be using different (production) wheels with hubcentric adaptors, or adapting the hubs if possible.

Wheel diameters are 15" and 16" and will go from 5.5 to 7.5" possibly.

Offset not hugely important as I'll be using hubcentric adaptors, but needs to be at least 35mm

Sorry if this is a bit open ended, but what production / aftermarket PCD should I go for?

The MG hairpins are a reasonably light wheel and plenty out there (6.5 x 16". PCD = 4*100. ET45) - and that PCD would give me a wide choice.

Wheels need to be quite tough as I seem to be a bit hard on them on kerbs..... Broken wheel

What is the current PCD ?

The 2 most common 4 stud is 108 and 100
108 is ford, peugeot, citreon
100 is vauxhall, vw, renault

then theres 98 which is alfa and fiat
114 which is randon japs
alot of japs inc Hondas and toyotas use a mix of a few IIRC, depending on who they were colaborating with.

Centre bore is the other thing to watch for, most aftermarket rims have large bores and use spigot rings to correct, but using OE rims can be a snag if the rim bore is too small.

95.25 X 4 (which almost gives the game away :-) )

100 X 4 or 108 X 4 seem like the most popular and the centre bore won't be a problem as the spacers will be machined accordingly.

MGF / MGTF may be an option on that PCD?

Yep that MG used the Triumph pcd as per original Formula Ford and most 1960s and 1970s racers and kit cars.

Yeah - it was the same PCD on my Formula Ford 2000.

Time to buy another Lotus I think.....!
