Default Is this what a Lightened Flywheel looks like?

As I've never seen a standard flywheel yet alone a lightened version I have no idea if this is what one looks like?
I was just imagining more holes around the outer edge thats all.

Thanks for confirming either way

Yup, its lightened but not by much. The very light ones have material removed from the outer sections to reduce rotational mass.

This I'm hoping is for a 6speed, how can you tell?
Its what I've just brought along with a new Excedy clutch.

Thats what I was thinking it would look like, guess there are different levels of lightness on the flywheels, my one being level one lol

This was what I thought I was getting

As you can see it much much more drilled out.......I'll call them Monday, possibly have the wrong one here?

6 speed are 240mm and the lugs are larger than a 5 speed. The xspec ones are rediculously cheap as the exact same flywheel in Graham Goodes is £495+vat.

The guys selling off the xspec stuff dont know what theyre selling so i'd get in quick if you want one coz theyre in short supply from what i've heard.

This is what I have brought, received today from Aztec, sure its right a 240mm so a six speed, just the drilled out holes I'm more interested in, i.e. should there be more, as per their web page?

The lugs measure about 12mm high too

I personally recon its the wrong pic on the web page, we'll see what they say Monday.

With the my new flywheel fitted it wont make the idle run roughly will it?
I wont have to get other parts looked at to level out the tick over?

6speed cars have the high lug on the outside edge of the flywheel for the cover to bolt to, 5spd are simply flat.............

I see, so it pretty sure I have the correct 6 speed flywheel then.
I mean the wheel was £250, the more milled out race ones are £400+ arent they?, sure this is the correct one just a bit miss leading webpage pic.

Looking at the wheel now I really cant see I'd feel any difference in the way the car drives, but there we go not to worry its a new flywheel any ways.

The rrp for an xspec one should be £400+ but theyre selling off the last 10 or so they have at £150. The ones theyre selling are better than the one you have because the weight has been taken from the outside, not the middle.

You WILL notice a difference with a stock vs lightened flywheel because what you have to remember is that the flywheel is always spinning. You've felt the weight of the flywheel, in simple terms, imagine that spinning constantly while the engine is running, then the clutch clamping to it (slowing it down), then when you press the clutch the engine becomes free again and has to rotate the weight again. The lighter it is, the quicker it will gather speed. Because its rotating, any weight taken from the middle is less effective than weight taken from the outside due to centrifugal force.

Basically, it makes the engine more responsive, it WONT affect your idle etc, just how quickly the car responds.

Your flywheel is a 6 speed one

Thanks guys for this info, most helpful as usual.

Hamster, did you mean the flywheel I have, do you think I would feel the difference with that?, even with its small amount of weight removed from the middle rather than the outside.
Obviously I'd feel more if it was the race spec one, holes all over it, but mine?

Hi Daz, you will notice a difference mate but I always think its a job worth doing properly as you wont have to do it again for a long time. The price between the one you have, and the xspec one iz £100 and get you a better bit of kit with the xspec but its your choice. If you're going for a decent clutch, go for a decent flywheel.

Doing the job right all makes sence, thats why I got the flywheel same time as new clutch, which is a Excedy PinkBox (if you class that as a decent one)only on 330bhp, not plans to run more, Aztec doing a good price for both, so went with that., I'll stick with what I got, have to have a budget some where lol, but will contact Aztec about the image just to make sure.

My mate Jamie has the exact same clutch/flywheel combo on his 440bhp classic 6 speed but next time he changes the clutch he's going for a lighter one to improve engine response.

Personally I wouldn't be happy using that flywheel because of it's construction but I guess many do, I also can't see many benefits from using it because of where the weight has been saved (try holding something heavy next to your body then further away )

I'd prefer to see the holes around the outer edge because they are close together where they are and a slight fracture could lead to a terminal failure and flywheel failures are never pretty!!!!

I've not even seen the standard flywheel, not sure on how that differs from my new one?
I do understand that outer holes are more beneficial than centre holes, but theres probably a lot more machining involved there, so hence the price difference of £250 mine and £400 super light ones, so its all relative.
If Aztec confirm the flywheel is right, and their webpage pic is wrong then fine, i'll be happy.

Just had a look on scoobyworld's site, their Excedy one is £500, another one is £355 and weighs the same as my new one, a bit over 6kg. Oh sure you get better kit if you spend more but have to stick with reality myself.

Hi Darren,

Replied over on the other thread. Flywheel is correct, 6 speeds can only go so light due to the construction and lugs. They are brand new aftermarket items to help get the weight as low as possible.

5 speed ones are completely different and go very light if customers require it (down to 4.3kgs).

Pics on website are generic 5 speed. Will get 6 speed pics on the new website.

Hope that helps.

Many thanks for replying, wasn't expecting to hear anything until Monday.
I can totally understand the reasons over the two flywheels, so I'm happy with that, was just concerned after seeing the webpage pic and my one.
Whilst your about can I ask you what you think this flywheel will perform like?
Appreciate you time and info, thank-you.
