    You can call whatever you want.

    A quick reality check will put you straight.

    Look back in history and you will find for instance the R8G had a strengthened chassis to cope with its intended use.

    Look at any 205GTI (modified or not) and you will see stress cracks at the top of the B pillar. In the engine bay you will see the plastic shroud under the windscreen lose its eyelets to chassis movement. That's how you know the car you're looking at has been driven hard and on wide tires, with more power than intended and so on.

    Some cars of the past have been indeed overengineered. The BMW 1800 TISA was only sold with a racing licence (only 200 made anyway), but that was a 1500kg monster compared to the puny R8G with its 800kg or so. Keep in mind these two cars are contemporary. Yeah, the TISA didn't need reinforcing, but it only had 130HP for all its mass.

    But that was then and this is now. I doubt any manufacturer can afford to make the car heavier than it has to be. More material, more work, less performance due to added weight. And money talks. Be sure that Renault and everybody else for that matter know what they're doing and in cut throat competition for small profits per unit you can't afford that. To such extent that Japanese cars have used undersized heads for their fasteners for a long time to save a penny a bolt. The rest of the gang caught up only in recent times. Rest assured they won't waste a gusset or a thicker profile steel if the car doesn't need it. I remember on my wife's 1988 EG Civic, if you put a wheel on the kerb, you could hear the difference in the door shutting noise caused by chassis flex. But hey, try it for yourself.

    Ahhhh what kind of a sh1t car owner am I if I'm not even measuring cracks in the chassis.

    Interesting, and fair enough!

    Do this Bowie (if you didn't reinforce your car yet).

    Find some sort of "jig" that you can replicate in the future and take some critical measurements of your car (length/width/diagonal between these two, height, vertical diagonal, door frame measurements, front frame rail distance and angle, etc). Repeat after a year of hard driving/racing/whatever.

    The "jig" can be a solid structure you can use for reference, something like that. You can of course, make one, but that's too much.

    See what happens.

    Yeah, and like you said, noise is power!

    Credit to you for mentioning tires, an issue most people on the road today are indeed blissful about. Totally agree. Best money ever spent.

    The Integra Type R shell was seam-welded. Honda lost some $10,000 on each car sold.

    But back to this thread, have you installed a bleed valve and turned up the boost yet?

    Show me one example where a chassis has cracked at the seems, because of bushes and sticker road tyres.
    My 16 Ts powered R8 spent a lot of time on the track, and in motorkhanas, and cracked at the top of the A pillars, and the bottom of the C pillars. The body flexed so much that when the rear window was removed for painting, I found there was just polished metal in the corners, the paint fully worn away by the rubber. The rear chassis rails detached themselves from the inner guards in the engine bay. The front sway bay mounts also broke off. Rear engine mounts broke off. Yes, some fatigue was present.

    Impressive!

    Now starting to understand why these old car guys aren't keen on doing burnouts all the time. Hadn't expected the chassis movement to be that great.
