Hello!!

i am going to buy some new rims.i think im goin for 17"..but maybe 18".
so i was wondering,does anyone have a clue what offset i need?
its nice to know when im sitting here surfing,cant find any good answer on this anywhere

I'm not to sure but but ET25 rings a bell ?

offset is ET in wheel speak. altough i dont know what et stands for

do u know what size rubbers uԚ´re planning on using as that would suggest how much room u have to play with betwee the outer arch, and the damper leg / caliper

what wheels were u after,as 17s arnt such a prob, where as 18s mat need a good look at uԚ´re setup.

lads on here have up to 19s and no rubbing, but have seriously invested some dollars on the susp. setup

well,i was going for the tsw kyalami 17",they fitted right on without spacers.but its unknown when they will come suddenly

so i just thougt...what the hell...so im gonna buy the tsw pace with spacers...and its 18"...maybe not the most "tuningfriendly" size....but to that im gonne buy some 15" or 16"'s

et 24 is standard 15" BBS offset

Am i right in saying the lower the number of of ET , the wider the wheels stick out? My Ronal LS's are ET25 and look at a little wider than normal (they are 7.5 rather than 7 inches wide, but still seem to sit wider)

i think the lower the number the more they stick out from the hub. ET25 is the ideal offset. My pina's are et28, hartge 16's are et25. Dunno what he 17's would be, depends on how wide they are really.

My split rims are et16 fronts and et18 on the rear so will stick out a bit euro stylee

I think et is the distance that the bit of the wheel that sits against the hub is from the center line of the wheel. I don't know exactly how to describe it. You have the center of the wheel that bolts onto the hub. So if you now look down on the wheel (when it is standing up like on a car) and find the center line from that direction then the et is how far that bit mentioned before sticks out from the center line. A low et will mean that it is very close to the center of the wheel which means that close to half of the wheel will be sticking out past the hub. If it has a high et than that bit is very close to the edge of the wheel which means that not much wheel will stick out past the hub.

I think this is correct, if you can understand it .
