I have had the brakes checked they are all fine. its just not enough bite at the end for me.

You need to reserve judgement on the brakes until you’ve been on track, & given then some stick Don’t expect them to be like those of other cars’ - they’re not servo’d, don’t have much initial bite, & require pressure (& heat) to make them work properly.
Sounds like you should perhaps modify your “road driving” a tad too, & save the real hard driving/late braking for the track
Ok didn’t realize they’re not servo’d. So even with the bigger calipers it will still have the same characteristics.
Oh well i’ve ordered them now. +point is that there in bright red so they’ll match the car. Lol. sound like a women now.
I find it hard to drive my skyline slow with all that grunt under my right foot and my drift car i use only for drifting, maybe because i have a roller skate for work (smart car). so when i get in the proper cars i get bit excited i suppose
But your right Mr Pesky must change my road driving!
LOL Mark
Seriously though, until you get the thing on track, you really won’t know what it’s capable of
PS You’ll need different braided hoses for the 4 pot calipers too - there goes another �60

mark, i don’t know if you have done any trackdays, but i found that after seeing just what a good car could do on a track, i have actually slowed down on the road.
You cannot safely get anywhere near the performance potential of an Exige on the road so it becomes futile even trying.
Well the first thing I would be doing is looking at the brake fluid.
Castrol SRF requires changing out at least every 6 months without fail… Leave it in there any longer and it starts to absorb moisture and will de-grade rapidly.
Not only that but at �30 per ltr it is very expensive too. My advice is unless you are prepared to do the regular maintenance and pay the price then get the sytem back onto a regualr high performance brake fluid. If you do change it make sure whoever does the job for you does it properly and cleans the system out well as the 2 dont mix!!

Is that actually the case on what is a sealed sytem, i cant imagine it absorbing that much moisture

Yes.
Ok…
As published by Castrol (they recommend changing it at least once every 18 months):
[color:“blue”]Castrol SRF Racing Brake Fluid is an ultra high performance product formulated specifically to satisfy the ever increasing stresses placed upon the braking systems used in international motorsport. The exceptional performance of Castrol SRF is due to a novel silicon ester technology pioneered by Castrol and unique to the extent that it has been granted patent-protection in numerous countries throughout the world.
Castrol SRF evolved as a direct result of Castrol’s ongoing Research and Development program for brake fluids which identified this silicon ester technology as providing considerable performance benefits when compared with conventional glycol ether borate ester fluids.
Following exhaustive laboratory tests at Castrol’s International Technology Centre in the UK, the final formulation for Castrol SRF was subjected to an extensive road-test programme on the Gross Glockner and Stelvio passes high in the Austrian and Italian Alps. It then underwent an independent track test program conducted by a famous Formula One racing team. Their assessment was that “Castrol SRF is the best racing brake fluid we have ever used.”
Subsequently, Castrol SRF was offered to top flight racing and rally teams throughout the world including most of the Formula One teams, the all-conquering Jaguar and Mercedes-Benz sports car teams and the Audi, Nissan and Toyota rally teams. Enthusiastic recommendation by these experts soon created an immense interest in Castrol SRF throughout the whole spectrum of national and international motorsport. Today, Castrol SRF is regarded by the international motorsport community as being without equal and it is chosen not only by factory-supported teams but by private competitors throughout the world.
[color:“red”] All conventional brake fluids used in cars and motor cycles are hygroscopic, that is, they absorb water from their surroundings.[/color] Strange though it may seem, the flexible hoses incorporated in braking systems are permeable to water and in time enough, water can find its way into the system via the hoses, and seriously affect the brake fluid’s performance. This water reduces the boiling point of the fluid (ie, it lowers the temperature at which gas bubbles begin to form). When these bubbles form, they turn a virtually incompressible liquid into a mixture of gas and liquid which can be compressed quite considerably, thus severely reducing the efficiency of the brakes. In this situation, a driver finds that the brakes feel spongy. Brake-pedal travel will increase and it may be necessary to ‘pump’ the pedal to get the brakes to function effectively. However, when the brake fluid reaches a temperature at which the water in the fluid causes gas to be produced, which is equal to the volume swept by the piston in the rake master-cylinder, vapor-lock occurs and the brakes become inoperative. When this happens, the first indication the driver has that something is wrong is when he applies the brakes. The pedal goes down to the floor and the car carries on at undiminished - and possibly fatal speed.
[color:“red”] The silicon ester technology in Castrol SRF addresses this problem in two ways. Firstly, Castrol SRF is less hygroscopic than conventional brake fluids - it absorbs less water in a given time. Secondly, unlike conventional glycol ether fluids, Castrol SRF reacts chemically with the absorbed water to reduce its adverse effects, thus preventing the fluid’s high temperature performance and safety margins from deteriorating as rapidly as they would otherwise do. [/color]
Castrol SRF exceeds the US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925, JIS K2233 and current SAE J1703 and is miscible with all conventional brake fluids conforming to these standards. However, mixing Castrol SRF and conventional brake fluids will reduce the benefits of Castrol SRF. It is strongly recommended that conventional brake fluid be drained from the system before flushing and re-filling with Castrol SRF.
The wet boiling point of Castrol SRF, 270˚C, is vastly superior to the minimum requirement of 155˚C demanded by the current US DOT 4 specification. The product’s typical dry boiling point of 310˚C is likewise outstanding. This ability to withstand temperatures in excess of 300˚C, and its superior resistance to the effects of absorbed water, have established Castrol SRF as the world’s premier fluid for the hydraulic brakes used in all forms of motorsport.
NOTE: DO NOT MIX CASTROL SRF WITH OTHER BRAKE FLUIDS

Personally, I’ve started using this stuff - recommended by Randy, & if it’s good enough for his Datsuns…

R600+ DOT 4 racing brake fluid
The R 600+ racing brake fluid is approved to be used in all DOT 4 applications. It has a dry boiling point in excess of 600�F (307�C) and is used by top racing teams in all types of competition (GP2, British GT, FIA GT, Sports Prototypes, BTCC, British F3, British Rally, Radicals, Minis etc.). Although it can be mixed with other synthetic racing brake fluids we recommend that you flush the system with R 600+ to ensure no residue left in the system.
Cheaper too - click - even if you need two bottles.
Ian
Given the lengths most of us go to with our cars, is �40+ every 18 months for the SRF too much to pay?
Going back to the wing part of the thread again what supports are these on the Ti Exige (Martin Edwards ???)
[image]tsuphoto.com - tsuphoto Resources and Information.
There not the same as the Eliseparts ones, are these the ones you do Rob ???
Graham
The Titanium car is Martin’s, & those are the mounts he makes - use the same bolt holes on the clam as the originals, but move the wing further back to enable the engine cover to open. I have the Eliseparts mounts on mine.
Thanks Rob, you wouldnt happen to have any better pics of them would you ???
Looks like i might be �650 lighter soon
No I haven’t sorry, Graham. Believe me, they’re fine - if they weren’t, rest assured that Martin wouldn’t have them on his car
No I haven’t sorry, Graham. Believe me, they’re fine - if they weren’t, rest assured that Martin wouldn’t have them on his car
Agreed the look really good - so much so that mine will be sporting a pair in the not too distant future . They’re well made and the real plus for me is not having to cut the rear clam. As Rob says the do mount the spoiler a bit further back but it doesn’t spoil the lines of the car at all.
