These Morimoto lights for the F430 - which also fits the 430 Scuderia by the way - are truly amazing. My friend from our local club bought these to try on first and they look amazing on his so I literally ordered mine 1 hour after seeing it. These retains the OEM look but outshines the stock lights by far so I am surprised they aren't consistently under backorder.
The weight on these are SOLID. I love that it does have some weight on it compared to OEM because it should rattle less with the weight + 1 more mounting point compared to the OEM's 3 mounting point only. Time will tell if Morimoto holds up with the notorious heat from the engine bay but with a 5 year warranty that should be plenty of time of usage.
Moving on to the service side, The Lighting Guru gives the best service I've had in a long while, and I spend $$$$$ for online shopping. Communication is a breeze and I love how they follow up with you from when you placed to order to the day the lights are getting delivered. Great logistics + service = I'll be a returning customer without hesitation and most importantly I'll be referring my friends knowing TLG will deliver.
