What's cooler than being cool? ICE COLD, or in this case a set of discontinued, ultra rare HAYASHI 961R centerlock alloy rims; CE28 and TE37 were so yesterday! We've been told by a reliable source that this is one of two sets currently rolling around in the country, IN-THE- COUNTRY....
Hayashi provides a mounting adapter that coverts the standard PCD from a 5-stud pattern to a single center spline. The wheel is mounted centrally. Pins in the inner rim face locate the wheel onto the adapter plate and helps keep the wheel permanently locked into position, no slippage here. A single 32mm wheel nut is then used to tighten everything up- hence the name Centerlock.
For extra safety measures, a spring lock pin would typically be used to stop the nut from undoing itself under load, however Hayashi has gone one step further to include an inner reverse thread into the center spline. The lock nut (middle item of the top picture) is the last piece of the puzzle. Firstly the 32mm wheel nut is fitted onto the center spline's outer clockwise thread, then followed by the lock nut which is fitted into the center spine's inner reverse thread, by having opposite threads, the two (wheel nut and lock nut) work against each other, effectively cancelling one another out and stopping any chances of the wheel flying off!
Style wise, its your classic 2pc deep dish 5 spoke race inspired alloy wheels. The face is anodized in bronze with a polish lip. Size and fitment is spot on for the S15 with an offset of 18x9 +20. To fit the wheels under the stock S15 guards a tiny amount of negative camber was dialed in via the camber tops; nothing out of the ordinary for a car that see frequent track use (no demon negative camber required here), a guard roller was used to flatten the inner lip of the guard for extra clearance and to help during heavy cornering loads. The rims are wrapped with 235/40/18 tyres; stretch is minimal, and retains a nice square tyre wall that fills the guards up nicely.
When the opportunity came up, Ben, like any other car geek, knew what these were about, and even though a brand new set of RAYS Engineering TE37 SL could of been bought for the amount he paid, he opted for these instead. The rarity and centerlock mechanism meant it was a no-brainer - our inner car geeks are super salty and probably will be for sometime.
