Hi all, just a quick couple of q's for you lot.

someone i know has a vr6 which he has broken and is selling the coilies and cat back exhaust. i take it these will fit my 8v?? i know there are threads on here which would give me my answer but i thought id be cheeky and lazy  and ask this wile i also ask...........

alloys, what size etc etc can i fit without knackering up the accuracy of my speedo?? as i want a set of 17's

cheers all

17's will fit as long as you run the correct tyre profile, however I think that generally 16" is the preferred size of most people. The coilies will fit, as will the exhaust but you may need a reducer.

cheers mate, so what is the whole 7j et blah blah blah all about??? i never have really understood those numbers and letters that you see stamped on the alloy

Obviously you have the diameter of the wheel which is measured in inches. You also have the width of the rim which is what you refer to as 7J, this basically means the rim is 7" wide, 8J is 8" etc.

Then you have the offset which will be stamped into the wheel, on a mk3 it will typically be ET30 - ET45 (standard wheels are ET43). This basically determines how far in/out of the arch the wheel sits. As you lower the offset the wheel will stick further out, whereas if you increase the offset the wheel will sit further in the arch.

For example, if you are running standard ET43 wheels and fit 20mm spacers the offset will be reduced to ET23 and the wheel will sit 20mm further out than before you fitted the spacers.

I'm assuming you understand PCD so I won't go into that

ah gotcha!!!

so what is it about wheels that feck ya speedo up?

here we go dom your gonna hate me, (may i claim a blond moment or at least fact im tired??) PCD?? i may know what it is but cant decypher what PCD stands for! hahaha

Stolen from a website as I cba typing it out:

The term PCD stands for (pitch circle diameter) and is the diameter of a circle drawn through the centre of your wheels bolt holes. PCD is measured in millimetres and also indicates the number of studs or bolts the wheel will have.

One of the most common fitment has 4 studs and a PCD of 100mm, hence the fitment 4x100. Check the fitment guide above to check the fitment of your car, if you are unsure please check with vehicle and wheel manufacturer before purchase and subsequent fitment.

With regards to messing up your speedo, you need to keep the rolling radius of the wheel the same. This means that if you fit a bigger rim you need to fit a tyre with a lower profile.

For Example if you put a 14" rim on you would need a tyre with a high profile (i.e. a big sidewall), whereas with a 17" rim you would fit a much smaller profile tyre (e.g. little sidewall), the rims are completely different sizes but the overall rolling radius of both wheels will be identical if done correctly.

sweeeeeeet thanks mate

+1 indeed

I ran 17"s for a while and given the choice again I would use 16"s

[gti gaz]

16s all the way 17s just  give you to much hassle and 16s handle so much better tats what i think some people think diffrent but each to there own if your not going to drive much 17s if you like to drive 16s
