Any recommendation for the chassis reinforce?

[Leo Exige]

So one of my friend who tracking his 2015 exige V6 a lot told me that after heavy track use, the exige seems loose somewhere and start to making nose everywhere.

 

And I will running my exige on track more and more so is there any chassis reinforce parts I can use to boost the stiffness before it’s too late?

 

Roll cage is not my option cause I need to keep it road legal. Where I live roll cage is not allow in a road car.

Front chassis brace is a good idea  

Having said that, it’s not as if the chassis is becoming flexible, it’s much more likely to be bushes on suspension components etc. Just enjoy the car and replace parts when needed and it’ll still feel fresh.

If you're going to be tracking your car a lot have you thought about replacing your Toe Links (which can, rarely, snap) with the ones from Spitfire Engineering?  They are much more solid and they also do a "chassis brace" which will help to firm up the rear AND provide some support for the rear chassis/frame.

Relatively cheap mod and very safety/reliability focused, but could make a difference.

Highly unlikely your friend's chassis is deteriorating, as with every car that's used regularly on track,  inspection of the condition of the parts attached to the chassis is key:

Dampers

Bushes

Suspension links

wheel bearings

CV joints

Engine mounts,

Exhaust system

By no means is that a complete list but a good start.

I have seen some people do this in Japan which looks quite interesting

Thank you William, always the most rapid reply from you. Any idea where can find a front chassis brace for exige?

 I will consider it when I decide to replace the stock bilstein to go with nitron, but if you told me those toe links will extra firm up the rear I definitely will do it. Especially I will get much more power than stock.

Thank you Arun for your clarity clue, so you mean there is no need to worry about this aluminum glue chassis at all?

there is a theory said that this chassis is stiff enough 15 years ago when it just released.

But nowadays especially the develop of the tire make the game change dramatically. And they are imply that it won’t handle super sticky slick tire well like M2C,718 or other modern sports car.

And that’s the reason the exige have much better power to weight ratio but didn’t seems to have enough advantage on track compare to modern sports car,Blah blah.

With the brace on it will be stiffer!

"imply that it won’t handle super sticky slick tire well like M2C,718 or other modern sports car" - and yet they have been racing for years with no issues etc. The hardest environment for any sticky tyres and chassis.  I'm not sure if you are worrying about the wrong things here re the chassis.

Well this look... interesting

I don't see how a (what looks like 50x6 flat bar) frame bolted in there can make the chassis more rigid?

Give Elise parts a call. It’s not on their website, but they can supply one
