Understanding brakes ?

Does anyone know the split between front/rear for braking in the exige.

I know you know this, but just to clarify my point …
On my GSXR1000 all the braking is done through the front brake, the back is mainly used only to settle the bike as I enter a corner. This is all due to the weight transfer during hard braking.

When a car brakes heavily I assume that the weight transfer puts more effort on the front. However, due to the engine position and weight distribution (which I am told is 60/40) on the exige, whats the contribution split (braking force) between front/rear ?

Im just curious because for a long time I had RS14’s just on the front. Blink Motorsport (who are awesome by the way) have just installed a load of bits onto my car, one of which was RS14s all round. The difference is massive.

Just interested …

And I’m just curious. I’ve never run anything but pagids in eight years and have always been curious about trying something different in the rears. Should I?

Cheers

The improvement in braking you felt when going to RS14’s all around is because you increased the braking force in the back.

As standard, the Exige has a 40/60 (F/R) distribution, which is typical of a mid-engined configuration and very good to apply power when coming out of turns.
It also has slightly more bias to the front than ideal, meaning that for the weight transfer you’re doing, there is enough weight still at the back so that you could use some more braking force to help it slow down.

When fitting RS14 to the rear as well, you just did that.
In fact, the car benefits from pads with a higher cf at the back than at the front, easy to say but difficult to do as you don’t want to mix pads with different temp/friction curves. They would behave different at different conditions.

I have experimented with lots of different pads and so far like the RS14 and PF 97 best. Both of them have about the same pedal feel, overall cf and temp rating. And although the PF are a tad more expensive, they have no rivets, which means that you don’t need to change them as soon as the Pagids.


And yes, experimenting with pads is Ok.
I mean, I know guys that are perfectly Ok with EBC greens… (depends on how you drive)

Cheers Uldis. The pedal feel is rock hard now and the stopping is simply awesome, it was the only part of the car which let it down before on track. Confidence should be much higher now with the brakes which is really important for me on track because I find braking is where you can make most ground on people (I know its not a race, but its fun playing with other punters). We will see tomorrow at elvington anyway. Cant wait. Thanks again.

Agree, like some people say… the pedal in the middle wins races…

There myself but in a Caterham - weather is looking excellent

The pedal feel is rock hard now…

Often caused by just having lots of pad depth at the rear.

Just to update everyone, the brakes were fooking awesome at elvington. I have recently had my geometry setup by blink and the front end of the car was absolutely planted. The car will not understeer now unless you miss your turn in point by about 1/2 mile.

My only problem is the rear of the car. After speaking to Johny (BAT) we put it down to the toyo tyres (T1R’s). Johny had used these and we came to the same conclusion - these tyres are utter shite. Ok for the road, pointless on track if you want to carry any sort of decent corner speed.

Yokos or Toyo 888s is it for a dry track.

Agree, the a039’s I had on before the toyo’s were far superior, not only for outright grip but for how they feel at the limit and beyond.
