GS F brake disc upgrade?

[hockeyedwards]

So just hit 45k in the F and had the 50k service, lockdown meant the usual 10k per year was down to 4! So an advisory was put on all 4 corners for the discs. I've had a mooch around online and not entirely sure where to source from, LPD have been unhelpful in other parts enquiries so I am not going that route and likely eye watering. I have the part numbers - both Lexus and brembo, but the thought crossed my mind whether there was an upgraded disc suitable for the GS F? Not that there is anything wrong with current braking performance.

Questions to the F gang are 1. Where would you recommend sourcing the discs from and 2. Do you know of/ have you upgraded/ is it worth upgrading at all?

I never intend to track the car, so I realise that is in the column against upgrades, but if a better disc was similar money, why not?

Ta muchly, ever used them before? Some automotive websites don't look very legit sometimes so a bit cautious of blowing money on these sites unless used by others 😛

Buy car parts are part of Autodoc, i use whoever is cheaper at the time. For brembo discs on my ISF £114 delivered when i bought mine! See thread below:

The only upgrade discs i found for the ISF were 2 piece (so they were lighter) and 7x the price at least, i assume a similar thing may be available for the GSF.

I bought a full set of discs a couple of months ago, as I know my rears will need changing soon. Thought at the price was daft not to get the fronts too.

used buy car parts - absolutely no problem. Bits came from Germany.....

The 4 brembo discs were £67 each. No brainer. Arrived within a couple of days. 

managed to pick some lexus pads up on eBay - so quite happy.

Much appreciated chaps, ordered all 4 corners 🙂 that'll give me something to do with the lighter evenings coming!

Thanks for that,great price for the discs compared to Lexus oem.

I will need pads also and I see they do brembo ones,but I believe there is a question mark as to whether the pad material will be up to the same spec as Lexus oem?

[Killysprint]

Unfortunately can’t answer the brembo pad question. But I’ve used EBC redstuff on the front of mine - no different in performance to the OEM but don’t produce as much dust.

bought a set of Lexus pads for the rear on eBay of £120ish.

I've just fitted redstuff to my ISF, brakes feel great and no dust!

Probably won't be, but not a bad thing considering the OEM ones squeal. OEM use Galfer 5032 material.

I also use Redstuff.

[Silkmen]

To add the the topic, I purchased brembo discs for ~£80 each. No issue with performance, however they aren't treated and look a bit nasty, see picture.

I don't ever recall seeing this with the Lexus discs which were removed, so I assume genuine Lexus discs are treated. To confirm the fronts look ok, the the rears look nasty and I'll be replacing them with genuine Lexus discs next time.

EBC yellow stuff pads work a treat though! Very happy with them.

Couple of coats of paint on the disc hub before fitting would do the job?

[Silkmen]

I had them fitted by a local indy and the issue became apparent after a few weeks. TBH I can't be bothered with all the messing about of removing wheels and painting etc. I'm hoping they dull and become less noticeable overtime.

As mentioned above, got EBC redstuff all around on mine. Will be doing same again when required. Same braking performance, much less dust.

My brembo disks from Autodoc came coated like the standard ones strangely enough. I noticed some of the other brands available didnt though.

I have noticed auto doc states coated aswell.  

 

Worth checking other places seeing if it states they don't. Will mean nobody has to worry about ugliness 

[Killysprint]

I’ve still got the ones I bought in their boxes in the garage. Will have a look in the morning, and check if they are coated or not.

[Killysprint]

Disc bells definitely have a paint coating / covering on them. 
 

Date code on the box label is from 2014....... not exactly going to go “off” though like a carton of yoghurt!!
