Me too.

I no longer have a car with a T9, but you might try reaching out to John at Quantum Mechanics. I know he has a fair amount of experience with the T9 and might be able to help: https://www.quantumechanics.com/

I had an '89 911 Carrera that I ended up selling to pay for my youngest daughter's wedding. Really poor timing on my part, because the market went crazy soon after. There really is something unique about the air-cooled Porsches. Wish I still had it!

Thanks Steve. I've run with some Radicals at the track days I frequent and actually prefer the car based engine in the Lola even though it's heavier. My son has more track experience than me so I let him drive it on track before I do. He's always faster than me in my own cars too! Ironic that my son and his YT partner Quinn just posted a video on the Lola. This is from Canaan which is a very short, relatively slow track. Some of the external shots are with me driving though.

I guess it's time to update this thread with the latest addition to my garage. For the first half of 2025 I had been looking for a more track-focused Duratec-powered Caterham to take over most of the track duties that my 310S had been fulfilling up to this point. That ended up not working out, so when this car showed up on BaT, I decided to give it a shot. https://bringatrailer.com/listing/2007-lola-b07-90/ It's a 2007 Lola B07/90 that the owner had raced in both historic and SCCA P2 competition. He raced it in the 2024 SCCA Runoffs and came in 11th with support and race prep from Wolf Motorsports in Elkhart Lake. He felt it was no longer competitive in SCCA competition so he put it up for auction and purchased an Elan DP02, IIRC. I have always liked the Duratec-powered Caterham SP300R, having a much more modern chassis with better aero than any other Caterham. The Lola would be a very similar chassis with a naturally aspirated Duratec and 5-speed sequential transaxle, instead of the supercharged Duratec and 6-speed paddle-shifted transaxle in the SP300R. Even with the BaT fee, it ended up cheaper than any other Duratec Seven I had hoped to purchase. Some details: Chassis: Aluminum honeycomb monocoque Engine: 2.0L Duratec, Jenvey 45mm ITB, TDC dry sump, appr 210hp ECU: Life Racing Dash: AiM MXG1.2 Transaxle: Hewland FTR 5-speed sequential, LSD, with integral dry sump tank Suspension: Ohlins dampers, Hyperco springs F: 450 R: 1100 Brakes: AP Racing Calipers, Girling M/C's with balance bar Wheels: Jongbloed 3-pc, F: 8x13 R: 10x13, (3) sets Tires: Hoosier slicks, F: 200/540x13 R: 275/570x13 Bodywork: 6-pc fiberglass with Zebulon/HRP CF dual element rear wing Weight: appr #1200 but we haven't had it on the scales yet So far my son and I have done 3 track days with it at NYST, Canaan, and the combined oval/infield at Pocono. Other than a charging issue at NYST, it's gone very well and we've had a blast every time. It's much more physical to drive than my Caterham, the Exocet, or the Miata's we've been driving, but it's been a really fun learning experience both out on track and in the garage. In fact, it's been an inspiration for both of us to get in better shape, and it'll provide a goal for my daughter and son-in-law to reach for when they gain more track experience. And what better reward at the end of a trackday than to get a hug from your 41 year old son thanking you for sharing with him the experience of driving a car like the Lola! Some photos from 2025:

The diff, check out photo 284. You can change the rear end ratio by just swapping out two gears in the back of the housing.

I don't know of any application that would swap in directly, but you might be able to fabricate a setup that would duplicate the dimensions of the Caterham end links. Check out the 'Ball Joint Linkages' section of this link at McMaster-Carr: https://www.mcmaster.com/products/rod-end-connectors/rod-ends-2~/ They also have connecting rods to work with male or female threads: https://www.mcmaster.com/products/rod-end-connectors/connecting-rods-1~/

Really nice collection Dez!

There are photos of the Titan setup in this build manual for the CSR260 starting at page 11:

Drag Reduction System. As used on F1 cars.

I just thought I would add one more data point to this discussion. I've done a little over 15 trackdays with my 2019 310S with the standard brakes and standard M/C over the last 4 years. I'm still on the original brake pads and have only done a yearly brake bleed for maintenance. The only time I use the parking brake is when it's on the trailer and I haven't noticed any unusual drag on the rear brakes. I'll admit that I was real easy on the brakes for the first couple of years, and only in the last couple have I started braking harder and deeper into corners. I just measured my brake pads and the fronts have between 7-8mm of pad remaining and the rears have around 2mm of pad left. YMMV, but I'm definitely getting more wear on the rear brakes with my setup.

I still have the 948 from my first car, a 1961 Bugeye, sitting in my basement. The bottom end has never been rebuilt, with around 70k original miles.
