I know the OEM bolts are fine and have been used successfully for years... But this time around I wanted to use ARPs.
The problem:
ARP does not make flywheel bolts specifically for DSM's so we have use the kit for a Toyota Supra. The Supra ARP bolts are too long to use with a stock thickness 4G63 flywheel. The good thing is there are 8 bolts in this kit so you get extra.
There are 2 things you can do to circumvent this:
1. Cut the ARP bolts shorter (what I did).
2. Bottom tap the threads in your crank deeper.
ARP part number: 203-2801 Link to Summit
Tools/Parts needed:
-ARP Flywheel bolts
-12mm x 1.25 nut
-Bench vise
-Angle grinder with cut off wheel
-Wire wheel in a die grinder, drill, dremel or whatever you have.
What to do:
1. Put the head of the ARP bolt in the vise and thread the nut onto the ARP bolt.
2. Usa a stock bolt to reference how much to cut off the ARP.
3. Cut the bolt as close to the nut as possible trying not to cut into the nut.
4. Flip the bolt around and put the nut in the vise, be careful it will be a little warm.
5. Back the bolt out of the nut and put the head of the ARP back into the vise.
6. Deburr the edge of the threads with your wire wheel.
Using this method I had no damaged threads at all and used the wire wheel to kock off any thin material left at the edges of the cut.
