Lamspeed Racing H13 Street Series Headstuds - Toyota G16E-GTS GR Yaris / Corolla

Details:

For applications where you have turned the boost right up over 30psi and plan to keep the head from lifting. This is the first thing that occurs from our testing when pushing the limits from when we set the World Record in our GR Yaris running a 10.5 @ 131mph to then setting the GR Yaris record around Sydney Motorsport Park at the 2022 World Time Attack Challenge with a 1.36.8

We are the first to develop and put into production an aftermarket head stud solution by taking our own measurements to ensure the studs are of the correct length so that they bottom out on the block, the factory bolts do not. 

These H13 tool steel headstuds are manufactured specifically for us and are much stronger than the typical 8740 chromoly.

Conventional washers are only 23-24mm OD, whereas our new oversize washers are designed to encompass the entire head bolt boss. CNC machined from 4140 chrome moly bar stock, hardened to HRC 45 and blackened for appearance.

Unfortunately with our Street Series we have not included the hex broach like our Pro Series to reduce cost and will suit majority of the market.

What makes our headstuds better than the competition?
- The dogpoint feature seats the stud in the blockand preloads the fastener for a more accurate and repeatable torque sequence. We also include the ARP ultra torque assembly lube with each set. Worhen it comes to headstud perfmance properly torquing the studs is paramount and we have made every effort to ensure torque precision and repeatability.
- Direct OEM replacement, no modifications.
- Made in Australia, beware of cheap immitations!
- Instructions are included.
