![]() ![]() If you could get these for 500, there may be some buxx to be made. parts to fit it to a soft top Spyder, you may be looking at almost 2k, which is about the same price as Japanparts new. The VG will create a vortex going counter-clockwise as viewed from the front. Still, 1000 for used is probably too steep, once you factor in freight + reconditioning of the hardtop (i.e. This assumes, however, that they are properly mounted in the right location.įor maximum effectiveness, my eyeball believes that you should mount them a little bit farther forward than most modern cars have them. Talon Hardtop Security System for factory hardtops with OEM latches. In fact, in aircraft, most owners do not report any change in cruise speed or max speed when using CG's. In fact, at track speeds (150mph+), VG's are totally ineffective at directing the airflow that far downard that quickly. Nevertheless, rest assured you don't need to be "at track speeds" for VG's to be doing their thing. I can't say, however, whether it will be a noticeable improvement. So anybody driving on the highway will probably get at least marginally improved mileage (less buffeting, maybe less noise). ![]() Those types of speeds are where the VG's are doing the most good. Or to retain good rudder or elevator control on the tail feathers at a high angle of attack. Lapdance, GABRIEL1, FormInFunction and 1 other person. More Pictures of my car with the top can be found at Group A Toyota MR2 Spyder Hardtop Group A Motoring. Performance Modifications Care, Maintenance, and Troubleshooting MR2 Spyder Main Forum Appearance Modifications Parts and Miscellaneous for Sale. Overall, great fit, very light, and relatively inexpensive. SpyderChat Forum is a community for Toyota MR2 Spyder Enthusiasts to discuss specs, reliability and more Full Forum Listing. They are used to get that Cessna to stall at, say, 46mph rather than 48mph, or to get a super STOL homebuilt down to a 28mph stall speed rather than 32mph. The company is based in California, so if you live in NY, it will take a lot longer to arrive. On aircraft VG's are considered LOW SPEED aerodynamic devices. So what are you gaining on a car? Well, interestingly, the VG's make the most difference at LOW speeds. 2 or 3mph with better control is more common on planes that are deemed to "really need" VG's. On some homebuilts, the VG's will lower the stall speed by as much as 4 or 5mph. The window appears to kind of be like a flap that is dropped down from the wing ("roof"). Similarly, your roof to your rear window looks a lot like the top of a wing at high angles of attack. there are some homebuilts (most canard planes come to mind) which get piss-poor airflow over the front horizontal stabilizer at high angles of attack (this is because they are laminar flow designs intended for high speed cruising). It's really such a ridiculously simple device and it really works well.Īs for how important is it. Realistically though, all they really are are a piece of 90* bend so you have a vertical triangle and a horizontal rectangle (which is glued down to the surface). Also an Airframe and Powerplant mechanic with a 4 year aeronautics degree.įirst off, most of the experimental guys who use VG's make them themselves or buy them for a ridiculously low price. Then you get to route the window defroster wire through the soft top sleeve and stuff but that's way too hard to explain without pics.Longtime Experimental Aircraft Enthusiast and Builder here.Run the seatbelt through the new plastic trim, install the reused plastic plugs into the trim and snap it into place.Mine came with 2 sets of bolts for the bottom hole, it didn't seem to matter which I used but I thought that was weird. Install the mounting posts using the supplied bolts.The HT should have come with 2 new trim parts with sections of them cut out to accommodate the hard top mounting posts. Remove the left and right plastic trim parts that the seat belt passes through (unbolt the seatbelt base).Replace them with the stainless latch parts.Remove the rear tabs near the engine hinge that are body colored painted on the Left and Right side.but if no one posts up I can send you a scan of the install info via PM on Sunday. It was a few years ago so I don't remember the actual instructions. Those things above aren't in any instructions but two things I noticed I messed up on the first hard top install. Did it come with all mounting hardware and modified plastic trim pieces?Ģ things on that - when you pull the seatbelts through the old trim pieces, be careful not to pop the retaining rivet off of the seatbelt when you pull it through the plastic trim that is being replaced.Īlso, when installing the new plastic trim using the plastic rivet(s) that holds it in place, do not push too hard otherwise you will 'crease' the trim and create a white mark from pushing to hard (like when you fold a credit card in half, you get that white stress line from bending plastic).
