Review: 2015 Megane RS275 Trophy-R + On-Board Video

[RENESIS VIII]

I recall a friend who had a GT3 with the racing clutch. It was a mega pain in the ass to do hill handbrake maneuvers and traffic frog hops were not fun. Eventually gave up that clutch for the standard soft-ass clutch. Less grip, less power but hella easier to live with.

And I'd drive a manual everyday over driving an auto anyday.

Your friend uses the GT3 as daily drive car?

Uphill.....tell me about it. Clutches like those 'ON & OFF' switch type is a real PITA for sure.

For those on & off type, that means every time you move the car, you need to step on the throttle to prevent stalling?

 

[Izso]

Yes, GT3 daily. Well, now no more. Changed to a XF Jag.

On-Off meaning the biting point of the clutch is extremely sensitive and low, so need to rev like mad otherwise stall but rev too much and you wheel spin and make a lotta noise.

Many years ago I drove a 240Z got the same effect like you. Step a little, engine stall, step to much the car surges forward, cannot control the clutch and accelerator timing.

I've test driven some Evo also with super heavy on-off racing clutch like that! Ugh, no good leh!

 

[Tom]

unless for circuit or drag racing, people should avoid these heavy clutches. It takes away the enjoyment of manual driving

 

[Shinjite]

Exactly, it is no fun when one keeps stalling the engine and bunny hopping during stop and go traffic

But good exercise and get bigger left leg also......hhahhahahahah

Left leg muscular

Live in places where there is less traffic jam occurring. Like my place in Ipoh

too many people upgrade clutch first before power...and even sub 200hp car using 300+hp (or higher torque) rated clutch...

those ceramic/metallic plate type and loceng kring kring type....for show "sound"

and later complains hard to drive, left leg muscle bigger than right leg etc etc...

race clutch/competition clutch is meant for the specific purpose...not slipping during competition...the rest doesnt matter be it noisy,rough,eating syncro and hard to press because of stiffer cover spring for grip....


if me even on uprated car power...i will still just stick to organic type plate and stop at heavy duty grade clutch cover....all other aspect doesnt really matter to me...

heck even in rally competition i still stick to organic clutch type...so do all my manual ride....

But I have also heard that upgrading the clutch will improve performance? Like I've always heard about 4G15 engine using 4G92 clutch will help to increase performance.

clutch replacement doesn't alter performance of the car.
you might be referring to the flywheel instead?

Unless your clutch is slipping to lose power, a stronger clutch does not add power, the power comes from the engine......

 

[Izso]

Renesis : It's the flywheel. And changing to a larger/lighter clutch/flywheel doesn't really do much other than change how the engine responds. Faster / quicker, that sorta thing. Perhaps your 0-100 will improve a little. But that's about it.

I think it is the flywheel then. What I have heard previously is something about Wira 1.5 changing into the clutch from Wira 1.6 which also requires something like modifying the clutch cover. Sorry, what I heard that time is in cantonese not in english, so I wasn't so sure what it meant.

Then I guess those who use those heavy racing clutch on street cars is rather pointless. No point in getting those Ogura Super Single Clutch

I've also heard about making the car easier to accelerate during uphill if 4G15 is using the clutch from 4G92.

upgrade bigger clutch=adding more surface friction..more grip...

and also directly adding rotational weight which is more inertia for engine carrying rpm while moving...


yep...no point using race clutch when stock clutch will be just fine for daily usage....unless the car also going to trackday/dragstrip

If I upgrade to a bigger clutch, will it have a longer lifespan than the smaller clutch?

 

[vr2turbo]

My turbo with 200bhp uses normal exedy clutch set only.....

If you reach red line, will it slip?

 

[^pomen_GTR^]

more or less still similar lifespan (and depends on the usage) but lets say the car/vehicle is used to tow something heavy..bigger clutch would be more reliable for that extra stress....

no slippage ler...oem vr4 clutch is designed for that level of power...

so do all other car...clutch size is already appropriate to stock power level (and usually have 30% more safe margin above factory engine setup)


like stock scooby wrx 250hp engine...clutch is capable to hold reliable power up to 320hp....so if my scooby didnt exceed that power level, no point upgrading the clutch... simple enough

I see. I thought these larger clutch will have a longer lifespan than smaller clutch before it wears out.

I've thought of this then. To maintain the soft clutch feel, can a car take an OEM clutch from a different car and equips it? Let's say like I have an upgraded 4G93T which makes 270hp but I don't want to use a stiff racing clutch. So can I take the OEM clutch from 4G63T (Evo 3) and use that instead?

 

[vr2turbo]

Yup, as bro. pomen mentioned mine is standard VR4 engine transplant together with the standard gear box, so is not a modded engine to sometime else....

yeap...thats what most people do to maintain stock clutch feel

 

[Tom]

To be honest, clutch plates last for years, like a handful of years if driven right, so there's no real reason to source for longer lasting options

Although the truth is, a simple misuse can burn the plate and destroy any life there is to it left. Even when new.

So, never grind the clutch with too much revs and too little contact, especially when ascending hills, or traffic light launches

 

[vr2turbo]

Yup, that is true fact. My VR uses normal Exedy clutch set and I use them for years. I change one set when engine transplant time and in between another set and that is 16 years already. Of course normal every day use not racing.....
