What length of stud do I need to order for HRC Mani?

Metric 18-8 Stainless Steel Full Thread Stud M8 Size

40mm length? or 50mm length?

thanks

bump!!

I just used 50mm on my star manifold, cant be too much difference. M8x1.00x50

The 8mm studs for a GS-T are a perfect fit. Order them from Roadraceengineering.com for $1 each. Make sure you get the copper locknuts and washers as well.

I'm going to be ordering them from McMasters since they have them in Stainless with the matching washers and nuts. Little bling bling. I just didnt know the right length to order so they wont interfere with the manifold.

Opps sorry I posted the wrong information for you. I just ordered mine from McMasters. Here are the part numbers I ordered.
8x : 93805A359 (M8 Size, 40mm Length, 1.25mm)
1x : 93475A270 (M8 Bolt, 8.4mm ID, 16mm OD, 1.4mm Min Thickness, Packs of 100)
1x : 91828A410 (Stainless Steel Hex Nut M8 Screw, 1.25mm Pitch, 13mm Width, 6.5mm H, Packs of 50)

Sorry I posted the wrong info before, I wasn't looking at the right thing. Hope this helps.

It does indeed. Those are the same part numbers i ordered this afternoon. I decided to go with the 40mm also. dont know what i am going to do with 100 ss washers though, lol.

Use 8 of them and be stuck with an extra 92 that you dont know what to do with. Thats my situation. Hell for the price though you cant go wrong.

what's McMasters web address?

Remember the Hahn manifold is larger than the star one. If the studs are too long they will hit the log. That's the issue I had with the ARP stud kit, but I managed to make it work.

So I suppose you dont remember how long yours were, lol. I figure 40mm will work since I measured the length of the stock bolts and that seemed to be the best fit.
