Passo a explicar o porquê deste tópico:
eu tenho umas Leon FR 17'' originais, 7Jx17xET38, e neste momento, uma vez que tenho os travões Brembo do Leon Cupra R, as jantes levam espaçadores de 16 mm, para não baterem nas pinças.
Pensei nas Leon Cupra R, em 17'', 7,5Jx17xET38, que sei não precisarem dos ditos espaçadores, mas andam caras.
Testei umas Toora T950, 8Jx17xET38, mas mesmo assim, precisavam de uns espaçadores de 0,5 mm.
Estou a pensar também nas Ronal R38, 8Jx17xET35.
Poderiam-me explicar este item das jantes, para que serve, como se mede e como funcionam os nº dos ET tipo 35, 38, 42. Quanto maior /menor o nº, o que significa ?
Obrigado

Não sei se te desenrrascas bem com o inglês, mas cá fica mais uma explicação detalhada
* Inset or outset
This is very important. Ignore this and you can end up with all manner of nasty problems. This is the distance in mm between the centre line of the wheel rim, and the line through the fixing face. You can have inset, outset or neither. This determines how the suspension and self-centring steering behave. The most obvious problem that will occur if you get it wrong is that the steering will either become so heavy that you can't turn the car, or so light that you need to spend all your time keeping the bugger in a straight line. More mundane problems through ignoring this measurement can range from wheels that foul parts of the bodywork or suspension, to high-speed judder in the steering because the suspension setup can't handle that particular type of wheel. This figure will be stamped on the wheel somewhere as an ET figure.
Inset and outset are subsets of offset and the relationship is this : positive offset = inset. Negative offset = outset. Typically you can get away with 5mm-7mm difference from the vehicle manufacturer specification before you'll run into trouble with the wheels fouling the suspension or bodywork. So for example if your stock wheels have an offset of 42mm and you can only find replacements with a 40mm offset, that 2mm difference ought to OK.
* No offset
* Inset wheel
* Outset wheel
* More inset = closer to the suspension?
It may sound counterintuitive, but when you increase the inset of a wheel, you decrease the clearance between the inner edge of the wheel and the suspension components. In the example below, the red wheel has a larger inset - ie. the distance from the mounting face to the centreline of the wheel is larger than that of the green wheel. The grey blocks indicate a stylised mounting hub, axle and suspension component. You can see that by increasing the inset (positive offset) of the wheel, it pushes the inner edge of the wheel and tyre closer to the suspension. Conversely, decreasing the inset moves the wheel and tyre closer to the outside of the vehicle where it might scrub and rub against the bodywork and wheel arches. It might help to think of this more in terms of overall offset rather than inset and outset. The most positive the offset, the more the wheel is tucked into the car. The more negative the offset, the more the wheel sticks out.

De qq maneira quase tenho a certeza que é ET35... estamos a falar de Leon 1M certo?
Mais ninguém se quer pronunciar acerca do offset das jantes 17'' de origem?
