why woukd you have top change wheels????

as in my post above you could fit 235/30R18 or 225/30R18 track tyres on your standard alloy, so no need to change

lmao sorry to burst your bubble but the standard size wheels are 17's and an 18 inch or 19 inch tyre is never going to fit onto a 17 inch wheel? Might be a little bit of a loose fit lol

Tyre code Diameter Circumference Difference
---------- -------- ------------- ----------
225/35 R17 589 mm 1850 mm -2.4 %
235/35 R17 596 mm 1872 mm -1.24 %
245/35 R17 603 mm 1894 mm -0.08 %
215/40 R17 604 mm 1898 mm 0 %
225/40 R17 612 mm 1923 mm 1.32 %

ths better
 
Lol that made my day a bit better for a bit lol really busy at work and that made me laugh the 245's are interesting not much difference there but I just checked and there is no track day tyres in that size either

you could go down to a 205wide track tyre, would still give more grip than a 215 road tyre

No I'm not going to go for something with a difference that high I know its not a lot but I can't be bothered with the hassle it could cause
 
No not cost the overall tyre size i don't want to change it too much also you have to be careful it puts speedos out and stuff.
 
you dont have to worry about the speedo as long as the rolling radius of the new tyre doesnt increase or decrease by more than 2.5% rom the OEM 215/40/R17 rolling radius as thats the official maximum deviation you are allowed to run.

however if you went for a 215/45 R17 tyres you would have an increase of 3.6% so that isnt an option. However all the above are legal options
 
On another note, the dash computer on my car has a winter tyre option on which allows me to increase or decrease my speedo readings by 5% to take into account different size rims/tyres that arent within limits.


Do you have this option on the Ibiza?

Nope, I dont think we do?
 
got my car remapped today by ecotune uk :D glad i went with it, should be sitting around 220/240 bhp, will be putting it on a dyno at the end of the month and ill get some vids upfor you guys :p

get it on a dyno dynamics, id be keen to see the figures then, but whatever you do, dont bother with a MAHA dyno. probably the most inconsistent and widely over reading dyno there is.
 
Nice ^^ do you notice a big difference in performance? Iv never heard of ecotune.

Hi Steve,

That's because we take a particular manufacturer and develop products specific to it before moving to other brands, if you were to browse the BMW forums, we probably tune more BMW's in Scotland, particularly when it comes to DPF OFF than anyone else. :)

In Glasgow we work in partnership with C&C Custom Stainless Exhausts in Hillington and generally we will advise what setup of exhaust would work best in a given application with consideration to what can be done in the software... as with Chris's car, Campbell made quite a special turbo outlet to drop the turbo temps and a specific sports cat to reduce backpressure assisting in spool up.:D

The good news is that we are now developing products on the VAG range, we may not have the marketing machine of the big brand names but we are beautifully connected when it comes to developing or indeed sourcing the best software that money can buy and we are always directly contactable for any questions or support.

Agreed, I am a big fan of Dyno Dynamics for development where you need to hold a car under load at certain rpms for fine tuning.. for this there is none better imo. In actual fact when it comes to a good clean read, the most accurate is always inertia... i.e, not braked. Can't beat the big heavy rollers for a clean accurate measurement..(so long as it's set up properly).;)
