You do understand your wrong right ? You do actually know they work correct ?? You think $200 is to much money for these ? And your basing your idea on what ?? Because in your eyes its just a small metal part what can it honestly do right, it must not actually work, hahaha. They have been proven time and time again to actually work. At the factory the subframe holes are actually larger then need be to accomodate any flaw in manufacturing of body and parts, all within a tolerable degree. Over time it wears a bit and the car, any car feels a bit roly poly . By closing that gap and making it solid, it actually has been proven to enhance the effects of suspension behaviour over surfaces, fix some trammling issues, and actually lessen body roll and shift, now if $200 for some small metal spacers that actually improve handling dynamics is too much, then how can you justify over $300 on a cai that ingests nothing but hot air and only improves sound ? Or $60 side markers, or $1000+ dollar bumpers that serve no function other than name and ugliness,... Im not flaming or trolling but for once i can say the price point is valid and not just a product being sold on name alone.

 

In response to both of you:

I understand the R&D involved but forgive me for saying it doesn't take a rocket scientist to figure out that rigid subframe mounts will reduce chassis compliance, allowing the suspension to perform better. All it took was an engineer or anyone who knew anything about chassis design to take a look at the under carriage and think "gee we can improve the suspension by doing _______insert thought here______".

If you guys feel like 200.00 bucks is a great price for 4 metal spacers that you can make yourselves on a hobby lathe, then by all means, it's your money.

Just an FYI, if you watched the video for these spacers you'll notice the test car they use to demonstrate the effects of these spacers on is a toyota vitz. Not much of a sports car with a lot of suspension slop right out of the factory. Not to discredit the credibility of the spacers by any means but the effect is less dramatic on cars coming out of the factory with properly refined suspensions. But hey, if you guys think you can feel that much of a difference on an S2000 for 200.00, you are a vastly better driver than I am. I personally would much rather save that 200 and spend it on a track day or two so I can get good enough to feel that kind of minute difference.

 

You do understand that you're wrong right? Grammatically and logically.

You literally have no clue how fasteners work. But, I'll entertain this thought... How do you know they work?

So, you're saying a subframe that is properly torqued will wear these oversized holes? Does this happen with wheel bolt holes too? because, that would obviously wear too since they are slightly larger than the studs...and that's only 80-90lbs of torque, while the subframe should be torqued much higher (believe 150lbs).

Again, where's the "proof"? Who has "proven" this? The guys selling you the product?


Point is, if the subframe is properly torqued, it ain't moving. If it is moving (you'll hear it shift, cause it's pretty audible), your subframe bolts aren't torqued. Pretty simple actually.

 

I've seen more than a few subframes get shifted while driving on track

That being said, I'd rather have my subframe shift, than have something bend or break. I'll pass on rigid collars.

 

you've actually SEEN them? that's pretty awesome...

I'm going to mark my torque down my subframe, mark it with whiteout and see how much it moves this weekend (PCA event on sunday). I'm no betting man, but pretty sure it's not going anywhere.

 

subframe will bend or break with those collars?

 

No he didnt say subframe will bend or break. Cars are designed with compliance and some give here and there. Movement of components is part of the design. I am not the designer of the S2000 chassis so I dont know the in's and out's but I think it is ok to say that IF the subframe does flex and move, it was designed to do so to achieve a certain bend/flex value. So by introducing these collars that might prevent that from happening and could have other effects on the chassis and something (bracing, bolts, etc) could start seeing stresses/movement that they were not designed for and could fail.

 

^^ actually it's more likely the subframe holes are oversized for fitment purposes. The chassis's are robotically welded but welding causes distortion due to heat. Holes tend to move from their "ideal" location as the chassis grows/shrinks due to the weld process. In order to make sure everything is correctly fit during the assembly line, subframe holes would be designed over sized to account for this variance, not to achieve a certain amount of flex.

 

it's not 4. it's 12.

I've seen the subframe shift from spinouts and sideways offs at the track. If the subframe shift didn't absorb part of the impact, who knows what else may have been bent or broken?

My wheels are strong enough that the weakest link in my suspension is the arms or knuckle. I've bent knuckles before.
