ShadowImg Posted November 27, 2006 Share Posted November 27, 2006 Alright folks, not quite sure where to toss this, so general ahoy. One of the final things I'm investigating about the 2.5GT prior to purchase is in regards to aerodynamics on the highway, specifically in windy conditions. My 2.5RS at 70-75 feels like it gets significant amounts of lift on the front end when running on stock wheels and stock size tires. Oddly, this feeling doesn't exist when running on the 225/45R17s on the Rota Tarmac IIs. When reading up on it back then, it was agreed that the bodystyle did have significant front end lift, and Prodrive produced their aero kit specifically to combat it. Now, my problem is I don't know that it even is lift, but assuming it is -- does the 05-07 2.5GT have a similar problem at these speeds? Assuming it's not, anyone have an idea of what gives that feeling? Is it just soft springs and downforce at high speeds? Lack of grip in tires? Heavier wheel weight on the S03s/Tarmac IIs keeping them planted more firmly? I've test driven the LGT, but it's hard to make the determination since the suspension/steering was so radically different it was hard to come up with exactly what all I was feeling differently. Hopefully some of you suspension/grip/dynamics gurus can tell me what I can expect or what I need to do to fix this if it does happen with the LGT as well. Note: I've only ever observed this at 70+, or in *extremely* heavy tail winds at 45+, which is why I suspected it to be an aero thing. Link to comment Share on other sites More sharing options...
