Rear brakes (discs and pads) with potential trackday use

[gashead1105]

Hi All

I've been a member on here for a while now but I think this might be my first post! Bought an Edition 30 in May last year as my day to day runabout and been very happy with it thus far.

Anyway, I have in the past had a Lotus Exige for trackdays and general hooning but I sold it a couple of months ago and it's replacement (V6 Exige) hasn't yet arrived. As a result I took the edition 30 to Bedford yesterday, where it performed rather well (surprised a number of caterham esq cars and touched 140 indicated down the back straight!) apart from (i) spinning the inside wheel up - which is probably a driver issue and not much I can do about it anyway given I've the DSG box and (ii) absolutely, comprehensively destroying the rear brakes.

I was rather glad I changed the front brake pads to Yellowstuffs, which performed admirably, but I thought based on past experience of mainly Renault hot hatches I'd get away with leaving the rears OE. Unfortunately that doesn't seem to be the case, the rear discs now have clear steps in them and the pads have basically disintegrated! I think that's  because the ESP won't fully disengage.

Anyway, cutting to the chase, do you have any suggestions as to replacements (rears only)? The car is mainly used on the road, which points to OE but there remains the possiblity that even once my new toy arrives I will still do the odd trackday in the golf in the future. Yellowstuff pads and OE discs? What is the current forum preferrence - I've had a quick search and can't find anything to hand...

Cheers Will

S3 discs as they are vented. I'm about to try Pagid S in the rear on mine. Not done a track day on them yet.

LSD for the inside wheel issue!

DSG boxes benefit from being mapped and are awesome on track.

Thank you. As I say I have another more track focused toy on the way so I'm not really planning to go down the modified route with this car. Given how urgent the problem is I've just gone for OE in the end.

Couple of questions though for my own interest. Is it really possible to fit an Lsd with the dsg box? I presumed that couldn't be done! Also, can you really separately map the box? I've remapped engine ECUs before for more power but don't want to up the power on this car and never thought you could do the gearbox separately. What changes does a map apply?

Actually I've just seen your avatar. What was the cost of your LSD if you don't mind me asking. That is the one change that I think would really benefit the car on a day to day basis let alone on track!

An LSD on a DSG box is in the region of £1400 parts & labour, I have a Wavetrac. I wrote a brief review of mine here: http://www.mk5golfgti.co.uk/forum/index.php/topic,90941.0.html
A stage 1 map (as I'm sure you know) brings about a transformation on these cars. Worth every penny. If you went for both you'd be bound to get a good deal I'm sure.

Very interesting! Thanks for the link, although it's to a thread of yours on the DSG map (which is also of interest). If you've written another thread on the LSD a link would be really good!

The problem is basically one of insurance, once you starting mod'ing the insurance gets more and more specialist and the market gets smaller and so more expensive. I've modified cars before (my last Exige was up to 270hpish with various engine, chassis and suspension mods) but for my daily run about I just want to be able to bung the reg into confused.com and come out with a £300 quote! I'm well aware though just how good the ED30 is when it's had a stage 1, but it still won't be as quick as the V6. However, a decent LSD would really benefit the car in its standard form in my view - I've had a megane 250 cup in the past and the LSD made the car.

Yep, wrong link! 
It sounds like you know what to expect and what it would bring to the car. My garage reckoned it to be one of the best modifications that you could do to these. I'd agree.
