It is important in engine preparation to mount bolt screws reinforced as they play an important role in the reliability of a racing engine.
You have two possibilities either you put reinforced screws on your original ladders or you put or change the screws of your forged ladders.
The first option is not recommended on an engine preparation with overpower (turbo or compressor) because the original buckets will not support the overheating pressure.
