Some Burning Questions!
« on: 08 September 2009, 16:15 »
Hi bros, I've got some flaming questions I've been waiting to ask. I did do a search and surf some threads, but I decided to cut to the chase because the GTI VI has more "electronic control" compared to the other cars I've driven and currently own.

To begin with, The Cosmetics.

Rims:
If I upgrade to 19" or 18" Rims, I'm planning BBS CX-R
(immensely in love with those design, as I've an obsessed by odd, yet striking designs.),
1) How do I go on deciding how, and which one to get?
Considering the fender rub, offset and if the car is on full load!
Heard that its ok within the range of 35 - 55.

1a) Any idea what's the lightest weight for an 18" or 19"?

My current rims on my Honda Jazz is 15" at 3.9kg per rim. And its lowered to 0 fingers!

2) Will there be any difference in the ESP and the Suspension Control, (Comfort and Sports mode) in the upgrade of the rims?
If so, how much, and how bad will it be?

Coilovers:
3) What are the best available in the Market that is Height and Damping Adjustable?

4) Any Airbags, or Hydraulics?  :drool:

5) Will the upgrade to Coilovers affect the ESP and the Suspension Control (Comfort and Sports mode)?
If so, how much, and how bad?

I hope nobody flames me as I know these Q's are the noobest of them all. But coming from a different platform, Jap cars, and as the GTI VI will be my 2nd car, I'd like to be educated on these as I may want to have them before purchasing my GTI VI.

Thank You very much!  :embarassed:

do 15's get to be called 'rims' - thought anything under 17's were 'wheels'  :tongue:

Providing you keep your rimmage size even between front and rear, it shouldn't have any effect on the ABS/ESP, though to be on the safe side, try and keep the overall rolling radius the same as OEM.

Suspension, again, shouldn't affect the ESP, but not sure on the suspension control thingy!  So you have the ACC?  :undecided:

Hey thanks a lot! That will be a great help! Could you also include some info as well!? like the ride height difference, any fender rub and stuff like that please! thanks!  :wink:

haha! i guess! sadly most jap cars here come with the "standard" 15" 'wheels'!  :laugh: :tongue:

Hhmm . . . from what I know, and this is what I've been hearing, you can inch up an inch from the OEM size. Well just one inch. although technically you can go further, from the mechs at my place said that anything above 1inch from OEM size, will put stress on the bearings and stuff. And they also said about something regarding the revolutions of the rims and bla bla bla! Don't how true this is though :undecided:, I only went on to 16" because of my 2.5" pipes when I went Turbo! Other then that I stuck to 15" and lowered, and since the "wheels" were 'small' and light, I managed to get at least 16km/L  :nerd:

And bro, by ACC, do you mean Coilovers?  :embarassed: :embarassed: :embarassed:

And although it'll be nice as it is at 18", I can't help but want to slap on those 19"s!  :laugh: :grin: :wink:

Are they still at primary school?  :shocked:

There is no clear-cut max size.  Providing you could get tyres with the same rolling radius, you could put 20s, even 21s - the crucial issue is the rolling radius when dealing with rim diameters.  Rim widths are a different issue - obviously the wider the rim, the more likely it is to snag on either the wheel arch (fender if you read Yankie english), or on the suspension strut.  Maybe it is the 1 inch wider that they were on about.

And as for 'stressing' the bearings - that will only be an issue if you noticeably alter the wheel centre - this is determined by the wheel offset, commonly given as an 'ET**' figure.  You really need to stick with half an inch, to not affect the bearings.


And they also said about something regarding the revolutions of the rims and bla bla bla! Don't how true this is though :undecided:,

No, they got that right.  You need to be ideally within 3% of your original rolling radius - 5% as an absolute max.  Otherwise you'll end up with an inaccurate speedo.

And bro, by ACC, do you mean Coilovers?  :embarassed: :embarassed: :embarassed:

ACC is the 'Adaptive Chassis Control' - a factory fitted option.  Basically a button on the dash can select one of three different suspension damper settings - controlled electronically.  Similar to the Audi Magnetic Ride, used on the latest Audi TT.  If you have this on your car, and then ditch them for aftermarkets, such as Koni FSDs, or full coil-overs - then the car might throw errors, because it wont be able to 'electronically control' the suspension.


Have a play with that VENOM website, trying different rim diameters and widths, and different tyre sizes.  Michelin and Toyo tyre websites are good for providing the full detailed specification of all their tyre dimensions.

Hey bro, thanks alot for the info. Great help!  :wink:

I discovered an ABT Dealer here at my place. And they're offering mods in 2 stages.

Stage 1: 260hp (still warrantied by the dealer)

Stage 2: 300hp (not warrantied by the dealer)

The dealer took me for a ride on stage 1! And I've to say, I'm blown away!

What do you guys think?
Is it worth it?

Its a whole conversion from the Stock GTI VI to a Full ABT GTI.

They're using 19" rims and it looks swell.
My dealer is using KW Coils and it rockZ  :laugh:
KW has done it all up to erase any codes that the ACC, (It DCC, Dynamic Chassis Control at my place) can bring out for the suspension mod!

Sounds good to me though!

Inputs please from the gurus!

I really want to! and if I do, I'm going for Stage 2!  :evil:

but what's the limit for our engine and gearbox? and the driveshaft and bearings?

if they're within the withstanding limit of 300hp or more, I'm going all out ABT Stage 2!
