Front Upper Control Arm Mount Reinforcement

Front Upper Control Arm Mount Reinforcement
What are the options for reinforcing the front upper control arm chassis mounting points on an ap1?
Anyone use this: http://www.junauto.co.jp/products/reinforc...e/index.html?en
A bolt in solution is very appealing.
Anyone have pics that show how this area differs on the ap2?

Spoon piece is not legal for SCCA stock class. It would put you in FP IIRC.
You need to follow the procedure in the TSB.

Pop noise at front upper control arm mount
Applies To: 2000-2004 S2000
If an oil canning or popping noise is heard when cornering or braking hard, visually inspect the frame rail where the front upper control arm-mounting bracket is spot welded to the frame rail. This problem only occurs to vehicles that have been driven repeatedly on a racetrack or in autocross events. If there is a gap
between the mounting bracket and the frame rail, use the following repair procedure:
� Bend the frame rail in towards the center of the car by placing a block of wood on the bracket spot welds and hitting the block with a large hammer.
� Remove the paint from the bracket and the adjoining frame rail.
� MIG weld the mounting bracket flange to the frame rail
� Refinish the paint to prevent corrosion.

MIG welding is easy and way cheaper than the Spooners and I can think of how it would be noticeably inferior.

Stitch welding the control arm is proven to work, the Spoon piece is overkill. Your choice if you want to do 'good enough for a race car on slicks' or 'will last at F1 braking levels'.
The Spoon one will definitely get you more points when listed as a mod for car shows. That's it's best use and main purpose. Paint it a contrasting color to help the judges find it.
