240M3SRT appears to be correct, from what can be inferred from LET's warranty info off of their website found at: http://www.letmotorsports.com/warranty.asp

Here's an excerpt:

LET Motorsports warrants to the consumer that all LET products will be free from defects in material and workmanship for a period of twelve (12) months from date of the original purchase. Products that fail within this 12 month warranty period will be repaired or replaced at LET’s option, when determined by LET that the product failed due to defects in material or workmanship. This warranty is limited to the repair or replacement of the LET part. In no event shall this warranty exceed the original purchase price of the LET part nor shall LET be responsible for special, incidental or consequential damages or cost incurred due to the failure of this product. Warranty claims to LET must be transportation prepaid and accompanied with dated proof of purchase. This warranty applies only to the original purchaser of product and is non-transferable. All implied warranties shall be limited in duration to the said 12 month warranty period. Improper use or installation, use for racing, accident, abuse, unauthorized repairs or alterations voids this warranty.

(emphasis mine, for the bolded and underlined section).

I found interesting that "use for racing" specifically voids the warranty, since many (most?) LET tuned and modded cars frequent the track. Heck, LET even hosts track day events... so, maybe they have the right to void it, but in practice might choose not to?
