To uprate or not to uprate (clutch)

Post by **Drax** » Thu Jan 09, 2014 3:53 pm

I currently run an OEM Exedy clutch & lightened flywheel but for the new build im unsure if I should uprate to something better.

It is primarily a daily car, but has been on around 8 track days now (no problems ever on the track) and I intend to do more track days with the new engine. i hear an Accord Type R clutch is a good option, but there are many other options too.

I don't really fancy anything too aggressive, but the new engine may require something to cope with the (hopeful) new power.

I would go ahead a get a new one as you don't want to have to go back in there soon after completing your build.

I got a 4 puk stage 5 clutch and it is honestly not that bad. I was expecting it to be awful but it isn't. IMO go for a 6 puk clutch plate as it will be easier on the road and up to the demands of the track.

Speak to competition clutches now they are a dealer on here. ACT will be around the same money.

I track my ATR and am using a standard Honda clutch. No issues at all...

Hated my uprated Exedy one around town, once it was warmed up. Juddered like hell!

I use a standard ATR clutch in my 5th gen and have had it on track many times. But that car is a putting out stock power. The ATR clutch kit is cheap too at around £160. It wont be able to take as much heat due to the organic compound though.

I've been using a xtd stage 3 and find it a pain for town driving and also it's wearing its way into the flywheel so maybe stay away from the ceramics if your in town a lot? I've read the stg1-2 xtd organic clutches arnt that good.

In my opinion the atr should be ok for your needs? Have you removed the clutch damper too?

Whatever you end up going for it would be best to get your flywheel skimmed/refaced.

Iirc your only suppose to skim the flywheel a very small amount? Is it .2mm?

I know mines past that with less than 5k miles

Yeah it is a tiny amount. Just enough to get any old material, scorch marks, or uneven wear off the face. I got my 4th gen's Fidanza skimmed as I was going to use a different compound (organic -> ceramic). We got Vanzep's ATR flywheel skimmed as it had a lip on it from the old clutch plate. We pay a local machinist £20 for refacing a flywheel.
