Saw a 05 plate with reg ending ZED near Bedford looking very clean and tidy.. Exhaust have a subtle note too ! 我從使用 Tapatalk çš„ Nexus 6 發é€

What about JIC Magic Spartan 505S .... Of course the poor man Spec full Stainless Not Ti! 我從使用 Tapatalk çš„ Nexus 6 發é€

Thanks Kyle much appreciated. Has anyone in this forum had installed the Megan racing exhaust? 我從使用 Tapatalk çš„ Nexus 6 發é€

I'm watching this thread, as it seem you have the superpower to find the good deal... Must feel epic like the TV ad! Hat off to you sir 我從使用 Tapatalk çš„ Nexus 6 發é€

Hi, you still selling the exhaust? Link above only to the decat.. 我從使用 Tapatalk çš„ Nexus 6 發é€

veilside z cheers, what are you thought? I would like the Tomei Titanium but in the Japan Domestic price which of course can't get in UK... So for now a cheap system would be better than a blown OE for sure haha 我從使用 Tapatalk çš„ Nexus 6 發é€

Good shout, I will give tarmac sport a shout and enquire some details . 我從使用 Tapatalk çš„ Nexus 6 發é€

Haha true drift spec I treat that just as a name, not because of rice! However just considering a single exit because of potential weight saving also. Been looking around for second hand parts but it seems on eBay only Japspeed coming up and seen a few bad reports over fitment issue... 我從使用 Tapatalk çš„ Nexus 6 發é€

Anybody have a Megan Drift Spec single exit fitted to their Z? Understand they are considerably cheaper and may not be as good as the more expensive variants out there. Any first hand experience would be greatly appreciated. Secondly if any one know a UK source or experience with a US source? Considering in US as low as Sub 400USD.... The reason for considering this is due to just bought the Z and the exhaust is blown so while fund is low but needing replaced anyway. I saw the Japspeed which the modification due to design fault is something I can't do myself so... 我從使用 Tapatalk çš„ Nexus 6 發é€

Ahhhhh... Why this come up when my bank is broke! 我從使用 Tapatalk çš„ Nexus 6 發é€

Welcome, I might actually see you about since I'm not far from MK. ! 我從使用 Tapatalk çš„ Nexus 6 發é€

Just offering my own 2p on this topic. Again I'm not a brake engineer or expert but this is my understanding. Below, is based on a snap shot of what the brakes are doing and not a dynamic modelling of brakes or chassis dynamic... A few simple equations is all it takes :- 1) Force = Pressure x Area 2) Torque = Force x distance 3) Friction force = Force x Mu (Friction co-efficient) 4) Pressure drop in break hose is neglectible 5) 1kg =10N ( Sorry I am working this by top of my head to keep the maths simple, for engineers out there he's its 9.81N) (Notice friction force does not taken into account of area!) Assumptions:- A) brake lines are completely rigid (although in real world it isn't but for simple cal it is ok) Pedal ratio held constant. C) Brake master cylinder not changed in all cases D) Example based on made up figure for illustration purpose only, not actual example of any car in reference. E) assisted braking is out of equation. For simple illustration purpose. Now assumptions are out of the road we can start... Break it down to smaller chunks. From up stream pedal to master cylinder to brake calliper piston, brake size.. Then later consider tyre and weight transfer. Pedal ratio Brake pedals work is a leverage. There is a pivot point which pedal rotate and where is apply forces to the master cylinder. Assume a ratio of 7:1. Assume you can apply 50kg to the pedal, the output force will be 7 time ( 350kg or 3500N) to brake master cylinder. There are you can see the pedal ratio have an effect on the force being applied to the master cylinder. Brake master cylinder size Assume cylinder size is 10mm^2, force of 3500N being applied. That means pressure of 350N/mm^2 in the break line. The higher the pedal ratio, as you can see can increase the pressure in the break line. Alternatively, decrease the master cylinder area can have the same effect. Brake calliper cylinders Now many people take about 4 pot 6 pot 8 pot..etc It is not necessary more piston the better. What is the key importance is the total piston area. That means the sum of all the effective piston area adds up. Recall earlier the equation Force = pressure x Area The force here is the clamping force. Earlier mentioned there is 350N/mm^2 (pressure) in brake line. That means if the calliper you changed has a larger effective total area your clamp force increases! But this is not the end of the story yet.... Therefore not how many piston you have, it is the area that matters! Brake pad Now assume your pad has friction co-efficent (refer to as My hereafter) of 0.4 . That means the fiction force being applied is clamp force x 0.4. That's why Mu is important, higher the Mu the mode friction force being applied to disc. Brake calliper distance to hub center Ok now you have the brake clamping force. What about the size...actually in this case size does matter. Brake torque = Friction Force x distance. In case you have center line of pistons are 300mm from hub center. That means the clamping force x 0.3. As you can see why brake size matters the bigger the disc the more of bream torque can be be applied!. Before you go and stuck on huge over size brakes, it is a trade off! Bigger brake usually means more in mass. In this case unsprung mass ( hurt your handling). Secondly, using aluminium bell would help but since the mass on the outside is the worst (moment of inertia) therefore base on this I think you should use the smallest you can get away with where possible. Higher the moment of inertia means more resistance to rotate. Well try holder a hammer close to the impact head and try hold it as far away as possible, and try to wiggle it about and for sure the further you holder it down the handle the harder to control. Same principle. Tyres 1) Refer to the friction force calculation, but applied to tyres. In this case it is the vertical load on tyre. Tyre grips better when there is a higher vertical load as ...Grip(friction force) = Vertical load x Mu. 2) Above is true to certain point, typical tyre grip will increase with vertical load but only to certain point and it will drops off. Therefore keep at the optimum point.(unfortunately tyre data are closely guarded secret for the tyre manufacturer) 3) Mu is always much higher when it is not locked up. As Mu is dropped very significantly when wheel is locked up. 4) Regardless of how good your brakes are, if you tyre can't grip you are not slowing any quicker! Therefore both goes hand in hand! Weight transfer Now since mentioned about tyre grip and vertical load. It is worth mentioning dynamically weight shifts as your accelerate, brake and turning. That's means your vertical load on each axle will varies during dynamic condition. Therefore it is key to exploits this limit of available grip which is directly linked to the weight transfer. For weight transfer, this is another topic, one thing we need is to know the center of gravity for sure. Track and wheel base will be needed to work out the weight transfer.... But I let some chassis dynamic expert to explain this much better than I can. However worth mentioning it is worth getting rid of or lighten weight up top. And keep weight at the bottom of the car will help lowering center of gravity which reduce weight transfer! Therefore keeping your cool sun glasses in the arm rest is much better than in the sun glasses holder up top!

Guys and girls been trying to search around on here but doesn't seems to find a comparison between Whiteline and Superpro bushes. By looking at the pictures it seems both employed tappered ends. What about grease retention feature where in interacts with the center pin? Any info anyone? Thanks. 我從使用 Tapatalk çš„ Nexus 6 發é€

Any pictures how it is when installed? 我從使用 Tapatalk çš„ Nexus 6 發é€

Cheers for the advice and clearing up. Although I have not made up my mind yet as to which brand to go with but I'm planning to have crack at this myself. (I think any bush is better than the perished one! Haha) I might able to get access to a press so that's half a battle won! Then again Im new to the zed hence asking. Tomorrow I shall have a chat with the chassis engineers tomorrow and see if anymore info or insight can be squeeze. 我從使用 Tapatalk çš„ Nexus 6 發é€

Previously on another car I replaced all the bushes with energy poly bush. Not sure I was happy with them except it make noise all the way and it was lubed as well. The more I search on forum it seems mix and match is the common trend. And more poly bush failing (inc superpro and whiteline) and gettin more confusrd by the minute haha. Hence why I was considering if I go through 2 of these bushes probably just equates to 1 of the white line/ superpro. 我從使用 Tapatalk çš„ Nexus 6 發é€

I have been looking around researching on the poly bush including trying the search button here. I came across this http://www.strongflex.eu. I'm wondering if anyone has any experience with them can offer some insight? 我從使用 Tapatalk çš„ Nexus 6 發é€

Thanks for the help. I will have a search for him cheers 我從使用 Tapatalk çš„ Nexus 6 發é€

Hi all, I have came across this example of 350Z from a trader, 54 plate service history but I have not visit and see it yet. However one thing I spotted is the bumper to front fender gap is uneven left and right hand side. Hence want to see your expert advice and view. Cheers Gary 我從使用 Tapatalk çš„ Nexus 6 發é€
