GTI/Pirelli Rear Bumper Removal

[tinto]

This is more of an issue with lighter coloured cars. Don't notice so much with black or graphite.

True. I won't be touching mine.
If I was had silver, yellow, or candy white on the other hand...
I'd neatly tape it off and plasti-dip (spray) it rather than mangle the bumper with my ham fisted removal DIY.

oh - Kryten, while I know you've complained about traction, your project isn't truly complete without a DSG reflash.
The K04 keeps on giving well beyond that current factory DSG shift point.

Check out the dubaddiction thread on it for GIAC info.
It should play well with your APR flash, assuming that doesn't have the same factory rev limit / soft cut applied to it.
I've heard rumours that APR are also coming out with a DSG reflash, but nothing firm as yet - may be worth an enquiry.

Excuse the OT.

Dogbone mount sorted most of those issues out for me, it's not perfect - but it's a huge improvement over where it was.

From what I understand the GIAC reflash for the DSG is a moot point if you have APR... I recall reading a bulletin somewhere (was it on the APR site, I dunno) that you don't need one if you have a APR reflash...

Anyway it's vastly improved, but at the cost of a little refinement.. Wheelspin is still there, but the wheel tramping is virtually eliminated, which means the wheels spin much more smoothly and for far less time.

Might be a different story when those 7kg wheels go on though.. erk.

Its easier to take the whole bumper off before removing the bottom section as there are tabs that hold it in. The easiest way is to work them loose from the other side with a flat bladed screw driver. I did this before getting my rear done. Brings the cost down if you can do part of the work yourself

do you have one of these for the standard gti bumper?

Tinto,

What's plasti-dip spray? I presume this is some spray paint in a can? If this is paint for plastic, where do you buy this, SupaCheap?

Ta!

the process is pretty much the same.

I guess the point would be - when are you shifting in S mode?
If it is in the 6000s, then I think you'd probably benefit from it, assuming the APR map is still feeding the engine at that point (sounds like it might be if they put out a bulletin).
You know... in the endless quest to spend another $900 to get 10hp

Which Dogbone did you go for?

I'd say it is more of a Bunnings thing - it is like a spray on rubber coating.
If you don't like it you can peel it off and it won't take your paint with it. Has a matte finish. A few thin coats and it can look pretty decent.

Dunno, when I'm on it hard I usually use manual mode and shift around 5,000... Power/torque falls away and shifting around 5000-5200 or so keeps you in that nice sweet band of torque.

I got the APR dogbone mount. Not a lot to look at, but it does a pretty good job... Takes a few days to get used to the increased vibration, then you're all good.. It's certainly a tradeoff, but when you want the power to the floor it's worth it... That axle tramp was a real worry, I was waiting for something to go snap, or worse - bang.

I got the impression that was the case with a standard GTI, but not the Pirelli / ED30
Maybe I'm misinformed - I'll go and re-read the dyno charts i've seen

Axle tramp is a horrendous sound.

I'll be getting it dynoed after the wheels go on, so I'll be able to see first hand!..

Certainly shifting at 5000-5250 gives you the bigger kick in the pants when compared to shifting higher though.

Back onto the topic,

There's a carbon fibre lower rear bar insert for sale
Item number : 120440498551

That would look quite good in that place that you want to paint.

I don't have an R32, Poyta. Completely different lower bar design.

[tinto]

Well I stand corrected.
I just looked at a couple of K04 dynos - power cranks on up after 5250 / torque fades on down (but doesn't drop off a cliff)
What counts for 'more' at higher RPM?
In any gear you'd already be hauling ass at that point, so is the torque as critical? i.e. more 'grunt'(nm) or more 'sprint'(hp)?

Swifter changes aside, I sort of can't see the point of flogging it beyond 6k now.
Right when I was itching to spend

Way OT... sorry. Hopefully it is interesting to someone other than me

[chrisgti]

leave the bar alone.. two tone looks good on the standard gti bar because its plain and needs breaking up.. but the pirelli bar has the extra moulding and looks perfect and more modern just the way it is.

there are only very subtle differences between the pirelli and the standard GTI bumpers. I think it looks unfinished the way it comes from the factory. But then its all a matter of opinion i guess.

I dunno what the dyno says, but on the track, shifting at 5000-5500 kept the RPMs right in the sweet spot of what felt like max acceleration. Come 6000 and it's well ready for a change.

All the funfun is in between about 4000 to 5000 under WOT.

Pretty sure that changing at 5000-5500 rather than taking it to redline would give you far superior 0-100s. Well, that's what it felt like anyway...

But who am I kidding, either way it's going to be hauling small horses ridden by mexicans.
