Cadiz vs Santiago vs Pretoria Weight in kg?

[rob1234]

(Bit of a thread resurrection, but for the record if anyone searches in the future.)

Swapped some wheels around today and took the opportunity to weight them - this is with differing tyres, so not scientific, but gives an idea...

VW 19" Brescia (5G0601025CL) with 225/30 P Zero:                          21.75kg
Skoda 18" Gemini (5E0601025AJ) with 225/40 SportContact 5:           21.35kg
Skoda 18" Neptune (1Z0071498) with 225/40 Pilot Sport 4:                21.20kg
VW 18" Belvedere (5G0601025CF) with 225/40 Bridgestone S001:      18.80kg

Hope this is useful for someone!

I weighed my Parker alloys with Bridgestone tyres and they were 22.5 kg.

The 18" OZ wheels I have on it now weigh 18.5 kg with tyres.

It does make a difference !!!

The car feels so much better, more agile & responsive.


Worth remembering that 19" wheels will gear the car up a bit, as they have 235/35 tyres which means a bigger overal diameter than 18" with 225/40, so acceleration will suffer.

And more thing that no one mentions....brakes..

The PP brakes are really heavy, calipers are 7.5 kg and discs are 10.7 kg.

(the non PP brakes are 5.5 kg and 7.7kg)


The Audi TT RS (Brembo) brake calipers are 4.5 kg and the PB Brake calipers are only 2.5kg (without pads though).



This is why my advice for anyone buying a GTI, forget about reverse cameras, pano roofs, leather, Santiago's, DCC, Dyanaudio and an outside toilet  and instead use that money for lightweight wheels and a brake upgrade, that's the way to make it fly

Are the Audi TT RS brakes a straight swap onto a pp GTi?
The advantage in the pp brakes over the standard ones are is they are better at stopping you, oh and they look nicer too 

[Jeff Wood]

yes and no....the standard calipers on the 7.5 are now 4 pot calipers, whereas the PP calipers are single piston, so probably not much in it, the difference will be that the bigger discs don't start to fade as quick, but that's not likely to be a problem unless you're going really crazy.

They do look better I give you that one

And you need a special caliper carriers to fit the TT RS calipers, Vagbremtechnic sell them, and they do a kit with the calipers.

But I'm beginning to like PB Brakes conversion kits, they look great, even lighter and theres an upgrade path to the rears as well. Not cheap though as you'll need their electronic handbrake gizmo, but its the only way to get rid of those ugly rear calipers...

Standard calipers on the 7.5 are 4pot? Are you sure?

[Jeff Wood]

pretty sure, I've read on a few sites;

Brakes (F): 312mm ventilated discs, 4-piston calipers
Brakes (R): 300mm solid discs, single-piston calipers


I'm trying to find more on the subject now

[cossiegaz82]

The calipers on a mk 7.5 are definitely single piston sliding type on the front, I had to strip the offside front caliper off on 2018 GTI at work today to retrieve a small stone caught between the caliper carrier and disc. 

[Jeff Wood]

fair enough, must admit I was surprised too.

and I can't find the review now where it said about the brakes, it's bugging me now 

[rob1234]

My 19s came with 225/35, which are only 0.46% off the rolling radius of 225/40 R18s.

Bizarrely, I agree you can feel the reduced weight though - pretty sure I’m not imagining it.

PP brakes are heavy (but feel good), but CS-S discs are c.900g per side lighter - for what it’s worth!

Pretty sure the Mk7.5 brakes are the same as the Mk.7.

[Jeff Wood]

The css discs are .9kg lighter that's where that weight saving comes from..and they're a direct fit if you already have the pp brakes...
