Inner fender removal for weight reduction?

So the car needs to go on a diet. More glass parts. Presently the car has J bars from the firewall and connecting bars under the dash to the A pillar bars . Is the
structural integrity of the unibody weekend significantly enough that additional bars need to be added maybe negating the weight loss gained by removing the inner fenders? What happens under the hood now that the inner fenders are gone? This is strictly a drag car. Already have fenderwell headers so the back is open. 66 Valiant. Who has run no inner fenders? My car is presently at 135mph. It was skating earlier at 120 then after some QA1 uppers and a good alignment it goes and stops straight. How does no inner fenders effect the car at speed? Not sure what the pros and cons are . Looking for some experienced feedback.
