Wheel Offset + PCD Guide


what spec are you running at present ? and how much room do you have at present on that spec?

in standard suspension at the moment. with some cheapy 15s that came with the car.

its supposed to have the oe 16s but some bugger must have swapped them before i bought the car,

ive been offered a set of et28 7.5 16s and just was wondering if they would scrub the arch when i eventually fit the coilovers.

but also there are et20s as well which i guess will stick out more, i dont want to have to stretch tyres just to get them legally in line with the body etc.

the trick is to know a base figure where you have to start when comparing. i could tell you compared to standard rims exactly what the differences will be but that's irelevant if you haven't got standard rims of course

you need the current wheel spec or try fitting a different wheel with a known size/spec and go from there

easy to do with the right info but don't forget even different tyre size/profile will affect the arch issue also

but i'm sure someone with similar size/spec will pop up and offer some info

that wheel offset calculater looks good- Im trying to find out what ET my wheels are. they are some multi stud Panther Wheels 4x100 and 4x108- theres a set on ebay but no width or et info!

generally though would an et20 in 7.5 x 16 be too wide?

standard ibiza/cordy 16s are 6.5x16 et35 is that right?

im going to see if can find anymore info from my wheels!

standard multispoke 16's are 6x16 et38

as for the 7.5 (et20) compared to standard rims above

1mm less inside - so no worries

37mm extension on the outside could be pushing it though if low low

i wouldnt be going super low as its a daily driver- so those et20 would be nearly 4cm further out- hmmm

damn just wish i knew what my et was on my wheels as the wheels im looking at are going to be gone in 30 mins lol

 

[Fl@pper]

if you take one off then measure it ? can get within a 1mm or so with a tape measure using it flat on the floor plus you might ??? even have it stamped on it somewhere with some luck ?

i'm guessing that it will be a positive offset rim so this is how

 

[Naz]

Im going to check when i get home- hopefully it will be stamped on the inside-


Ive let the et20 7.5s go as i reckon they going to stick out too much

 

[Fl@pper]

doesn't sound like they would leave much room for spacers if needed that's for sure

 

[Naz]

i hope et28s 7.5 will be better!

I'm running 7.5x17's with ET32 and there's not much room at the back. You might get away with et28 but not if you're lowered.

I'm running 6.5s on the back with an ET of 25. When wound right down on the coilovers I had scrubbing issues. The car's now approximately 100mm down at the back and they just clear.
