Caveat Emptor!
If this helps, piece of mind knowing the aluminum front is now more ridged and will flex even less even during street use.
) was unaffected by the bar. It seems to me that initial turn-in is about the same as stock, but the difference that I noticed was the stability during medium speed sweepers. The front end now feels as if both sides of the car are playing the same game in 80-90 mph sweepers. I was able to push my usual top speed through on of my favorite corners up by a full 5 mph with the feeling that I could wring a little more out of it without pushing 10/10ths.
I finally got a chance to get the car out of the shop and give the STMPO bar a test drive. Unfortunately, it has been a long time since I've had the car out on the road so I can't give a real back-to-back, with and without driving analysis. But I hit the road and took the car on familiar roads so that I could get a feel for the handling characteristics of the new set-up as compared to previous experiences.
Initially I was very impressed with the finish of the unit. It was very well packed, promptly shipped as promised and it looked great. The welds looked immaculate and the paint job was flawless. It even had the STMPO logo painted on the bar (more on that later).
The bar came with no installation instructions, but after removing the OEM tie-downs it was obvious how and where the bar fit. The bar slid tightly into place with very little "persuasion" needed and it tightened up using the OEM bolts from the tie-downs. I was relieved that the fit was so tight as I did not want to pull or push the uni-body frame ends in any way at all. The fit of the bar made those issues moot.
Unfortunately, the paint shop painted the logo on the wrong part of the bar. The logo pointed up so that, if you could see it from under the hood, the logo would be visible in that orientation. Fortunately, Ross supplied some STMPO decals, so I applied a silver one to the front of the bar so that it can be seen through the front grill. It's a very aggressive look IMO.
One thing that Ross failed to mention is that the plastic shroud must be trimmed to accommodate the bar. I didn't do such a great job in that aspect of the install, but I don't think it's very visible from the street.
As far as the driving experience is concerned, I think the STMPO front brace delivers on its promise to tighten up the front end. I have a '91 with NSX-R suspension, Dali street/track sway bars and 225/16 fr and 275/17 rear Azeni rubber. My impression of the bar is that the ride quality (if you can use the word "quality" to describe the NSX-R ride
These are just initial (and unsolicited) impressions of driving with the STMPO front brace for one day, but IMO Ross has fulfilled his promise with this offering.
FWIW the backing nuts are not aluminum. Hope this eases someones mind.:wink:
STMPO Front Chassis Reinforcement Bar installed on FXMD's "Project NSX":
Using the strong 3-bolt tow-hook brackets to tie the front frame rails together was a fantastic idea. By having such a big surface area to attach to on each frame rail, and the location being very far forward on the framerails, all of this greatly increases front-end rigidity.
Great product, great price, highly recommended.
