NSX-R vs NSX Coupe (91-94) Rear Strut Tower Bar

[piran1]

Just wanted to share with those interested the difference between NSX-R Rear Strut Tower Bar and the stock NSX Coupe (91-94) Rear Strut Tower Bar.

The stock 91-94 bar (P/N: 74691-SL0-010) is made of thin-gauge tubular steel and weighs: ~0.6kg or ~1.3lbs

The NSX-R bar (P/N: 74691-SL0-Z10) is made of a much thicker steel and feels nearly solid. Weighs: ~1.2kg or ~2.6lbs







Don't really have any info if there's any performance difference, unfortunately.

wow, the little things.

 

[piran1]

I was surprised too. Anyone else have this installed on their cars?

 

[RYU]

wow, nice tid bit of info there.

 

[piran1]

Always something to learn about the intricacies of these cars.

Good find! What's the cost difference?
Also, are the holes larger on the NSX-R bar?

Looks like the price of the NSX-R bar is (or was) twice that of the standard. (roughly 70 USD v. 35 USD). And yeah, it almost appears as though the R bar uses M10 and not M8 bolts?

This is very interesting. NA2 Coupes and Zanardi's didn't have this bar but it looks like 02+ NSX-Rs did (from photos I found on Google). I'm going to have to pick one up. Thanks for the part number.

Yes, the holes are bigger. I just used the new Honda bolts that came with it (still M8 thread). I didn't price a stock one, but it's really cheap for a small-run OEM part.

No problem! I see that theNSX shop has it listed on their website. Also, other NSXPrime vendors like A-S Motorsport probably can get it as well.

Cool find. Good attention to detail.

Notice any difference in feel?

No idea as I haven't yet driven the car this year.

Thanks for the comparison, the pictures and weights really tell the tale.

The original bolts used on the coupes do not properly fit the NSX-R strut tower bar. The correct bolts to get are part # 93404-08020-07. These are the same bolts that come standard on the targa. The difference is that they're black instead of silver and the washer has a larger diameter.

This is how the bolts look on the stock coupe....

This is how the bolts look on a real NSX-R....

The stiffer bar has been around for a lot longer than that. The bar first appeared on the 1992 NSX-R.

Glad I was able to pick one up before it was discontinued. Thanks OP!

 

[piran1]

No problem. Anyone who installed, provide your driving observations.

If anyone on this Forum, can detect the differences that this item makes when installed on your NSX, you need to be an F1 development Driver!

I didn’t buy it for the performance. I bought it for the bling, being honest.

FWIW the part is now available again. I just ordered/received it a month ago.
