Advice On Which Pads For 90% Track

[Jonmurgie 2]

Time to fit some new pads to my Wilwood 4-pots and checking out the Rally Design website I'm presented with the following options:

 

POLY 'B' / 700 - 1500°F

High friction over wide temperature range, consistant pedal, minimal pre bed required.

MEDIUM / HARD RACE APPLICATIONS, HARD RALLY, EURO CAR, GROUP A

 

POLY 'D' / 0 - 800°F

High cold friction, low wear rate and easy on discs. Good fast road pad with no bedding in required. Consistent pedal feel hot or cold.

FAST STREET, LIGHT RALLY, LIGHT RACE

 

POLY 'A' / 450 - 1300°F

Severe duty race brake pad, long life, high friction, easily bedded and reasonable cold performance with extended rotor life.

HARD RACE, ENDURANCE RACING, INTERNATIONAL RALLY

 

POLY 'E' / 0 - 900°F

Low wear rate, extended rotor life, very high friction from cold, ideal for high performance road vehicles, Cosworth's, Subaru's, etc.

FAST ROAD, LIGHT RALLY, LIGHT RACE

 

POLY 'Q' / 0 - 900°F

A ceramic enhanced formula offering quieter stopping, low dust, long life, quick recovery and high fade resistance - the ultimate road car pad.

FAST ROAD, LIGHT RALLY

 

I'm thinking POLY D or E really... or should I try the A?!

Depends on how you brake really, Any left foot braking? But I would buy a couple of different sets and see how you get on, Sets A or B myself

[Jonmurgie 2]

I brake early and light at the moment... and haven't ever tried LFB cause I'd be through the windscreen in no time! It's all something that I need to learn and improve on (tuition is on my list to do when the car's back on track!)

If you wanted something other than the willwood material, draw round the pad shape fax / talk to Questmead, they do mintex material pads, .. m1155 would suit 90% track. A friend with a tvr and the superlight caliper did this not long ago, he is much happier now.

Since it's pure track/race car I would go for A or B.

I would probably start with B and change to A if there are problems with keeping the temperature in the correct range.

But it's a light car and if you mostly brake lightly the B may be ott.

my mates 205 has the poly Ds and they dont suffer at all on track. I reckon As would be OTT, and possibly even Bs as 205s dont weigh much.

 

Do they not do a C grade?

Hi Jon

 

it's important to look at the friction ratings and match them to your rear pads. Also ideally you want a pad where the friction and initial bite are consistent and driver friendly. See if they can get that kind of info for you. DS3000 / DS2500 front with DS4003 rear would be my vote.

I have Mintex 1155's on the rear... will look at getting 1155's for the front then as I'd be happy with those I reckon

[Jonmurgie 2]

Just spoken to Questmead, very helpful people they are too! These are the options for Mintex:

 

1144 - £43 + VAT

1155 - £76 + VAT

1166 - £68 + VAT

 

Anyone have experience of the 1166 pads as those are what I'm tempted to try out

[johnrobertgordon 0]

Padgid (spelling?) blue's. Cant fault them. Pricey though.

Jon, Neal at DES uses them on his 205 (with 405 Mi calipers).

 

They perform well from cold and its not like they need to get hot to work but more that they start off ok and just get better and better.

 

I also had 1155's in the 306 at Llandow and even with 1200kg+ they performed perfectly.

I ran 1166's on my integra type-r a few years ago: they were IMO too hard even for track use while on road tyres (and useless on the road). If you're running slicks and decent 4 pot calipers then perhaps they begin to make sense, otherwise you most probably find that you cant get them up to temperature and they feel like wooden blocks under your foot. Too hard means reduced feel. Also, your disks become the consumable part, while the pads last for ever...

 

I use 1155's on the front of my 205 race car (780kg, Alcon 4-pots, bias-box, no power assist, 205 section Toyo T1R tyres) and to be honest they're probably still too hard.

 

So my take would be, definitely 1144's (or standard pug items) on the rear, and if you're on slicks, 888 / A032 type tyres or even just wider rims then 1155's; if you're on standard 195/15 road tyres with standard breaks then 1144's will probably be right.

 

cheers

I'd second this advice. I use DS2500 pads on the front and ferrodo premiers on the rear. The pedal feels good cold, but just gets better and better as you keep abusing the car. I'm only running std brakes, but they are more than enough I'm running A5239 tyres for track use.

[base-1 17]

DS3000s in your car I reckon, you wouldn't suffer on 2500 though until you step your braking technique up a level

[smckeown 1]

read recently the mini cooper s works cars run 1166s on the front and 1144s onthe rear. But then again my car is a lot lighter thyan that, so i'll stick with 1155s i think
